Re: error with delta import

The case in point is DIH. DIH uses the standard DOM parser that comes
w/ JDK. If it reads the xml properly do we need to complain?.  I guess
that data-config.xml may not be used for any other purposes.

Re: Issues with facet

2008-10-22 Thread prerna07



Thanks, it helped.

We were using *_s fields which had analyser section.

We used   to copy all fields in some other field type and used
this new type in facet. It is working fine now.

Thanks,

If that is the case you should look @ the DataImportHandler examples
as they can already index RSS, im doing it now for ~ a dozen feeds on
an hourly basis. (This is also for any XML-based feed for XHTML, XML,
etc). I find Nutch more useful for plain vanilla HTML (something that
was built non-dynamic), since otherwise you can bring your DB content
in that you would have to the page to begin with. As well as Nutch
for other types of documents I think (PDF) and anything that Tika (http://incubator.apache.org/tika/
) can extract.

Grant thanks for the response.

A couple of other people have recommended trying the Nutch + Solr
approach, but I am not sure what the real benefit of doing that is.
Since Nutch provides most of the same features as Solr and Solr has
some nice additional features (like spell checking, incremental
index).

So I currently have a Nutch Index of around 500,000+ Urls, but
expect it to get much bigger. And am generally pretty happy with
it, but I just want to make sure that I am going down the correct
path, for the best feature set. As far as implementation to the
front end is concerned, I have been using the Nutch search app as
basically a webservice to feed the main app (So using RSS). The
main app takes that and manipulates the results for display.

As far as the Hadoop + Lucene integration, I haven't used that
directly just the Hadoop integration with Nutch. And of course
Hadoop independently.

Which Spider did you use?

How does it compare to Nutch?

There is a patch that combines Nutch + Solr. Nutch is used for
crawling, Solr for searching. Can't say I've used it for whole web
searching, but I believe some are trying it.

At the end of the day, I'm sure Solr could do it, but it will take
some work to setup the architecture (distributed, replicated) and
deal properly with fault tolerance and fail over.There are also
some examples on Hadoop about Hadoop + Lucene integration.

How big are you talking?

Normally you don't have to start Q, but only "reload" Solr searcher when 
the index has been copied.
However, you are on Windows, and its FS has the tendency not to let you

able to copy the index from U to Q?  How are you doing it?  Are you

Re: How to search a DataImportHandler solr index

2008-10-22 Thread Matthew Runo

DataImportHandler is only a way to get data into your index, from a  
relational database of some sort. It won't affect your Solr reads in  
any way - so everything that Solr normally does will still work the  
same.


(I have not had a chance to look at it in depth, but searching the  
index would be the same as it 'normally' is).

What does your schema look like?  I am guessing you are using dynamic fields and
have an analyzer on the type for fields that are '*_s' that uses
WordDelimiterFilterFactory with generateWordParts="1".

  http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters

Since facets use the indexed values not the stored values, the indexed value
for "productIndex" would be 3 terms 'product', 'index' and 'productindex'

I believe that both of these are a result of the Analyzer you are using on your

Re: Re[6]: Question about copyField

2008-10-22 Thread Shalin Shekhar Mangar

If you want your indexed value changed, you can use an analyzer (either
PatternReplaceFilter or a custom one). If you want the stored value changed,
you can use a custom UpdateRequestProcessor. However, taking care of this in
your application may be easier than bothering with the two particularly if
you have to create your custom plugin.

Here is it, regex is very simple:















But the problem is not about the filed type. The problem is: how to retrive

RE: Issue with Query Parsing '+' works as 'OR'

2008-10-22 Thread Lance Norskog

URI encoding turns a space into a plus, then (maybe) Lucene takes that as a
space. Also you want a + in front of first_name.

A AND B -> +first_name:joe++last_name:smith

B AND maybe A -> first_name:joe++last_name:smith

Some of us need sample use cases to understand these things; documentation
with only technical definitions don't help much.

I am working with nightly build of Oct 17, 2008  and found the issue that
something wrong with Query Parsing; It takes + as OR

e.g. q=first_name:joe+last_name:smith is behaving as OR instead of AND.
Default operator is set to AND in schema.xml 


Is there any new configuration I need to put in place in order to get this
working ?

Re: Out of Memory Errors

2008-10-22 Thread Jae Joo

Here is what I am doing to check the memory statues.
1. Run the Servelt and Solr application.
2. On command prompt, jstat -gc  5s (5s means that getting data every 5
seconds.)
3. Watch it or pipe to the file.
4. Analyze the data gathered.

I'm with you all the way on this.

A parser which accepts non-well-formed XML is not an XML parser, since the
XML spec requires reporting a fatal error.

It is really easy to test these things. Modern browsers have good XML
parsers, so put your test case in a "test.xml" file and open it in a
browser. If it isn't well-formed, you'll get an error.

Here is my test XML:

Here is what Firefox 3.0.3 says about that:

XML Parsing Error: not well-formed

RE: Re[2]: Question about copyField

Yes, using fieldType, you can have Solr run the PatternReplaceFilter for
you.

So, for example, you can declare something like this:
--
  
...


  
... Put the PatternReplaceFilter in here. At least for indexing, maybe
for query as well

...


...

I would suggest doing this in your schema, then starting up Solr and
using the analysis admin page to see if it will index and search the way
you want. That way you don't have to pay the cost of actually indexing
the data to find out.

Re: Index updates blocking readers: To Multicore or not?


We shread the RSS into individual items then create Solr XML documents to
insert.  Solr is an easy choice for us over straight Lucene since it adds
the server infrastructure that we would mostly be writing ourself - caching,
data types, master/slave replication.

We looked at nutch too - but that was before my time.

RE: error with delta import

2008-10-22 Thread Steven A Rowe

Hi Shalin,

I wasn't talking about the behavior of parsers in the wild, but rather about 
the XML specification (paraphrasing):

1. An XML document is not well-formed unless it matches the production labeled 
document.
2. Violations of well-formedness constraints are fatal errors.
3. Once a fatal error is detected, an XML parser MUST NOT continue normal 
processing.

So although there are undoubtedly parsers that will parse '<' in attribute 
values, in so doing, these parsers are non-conformant with the XML 
specification.  This is important only to the extent that people who create 
documents that target non-conforming features of parsers can't reliably expect 
these documents to be parsed by conformant parsers; XML's 
write-once-parse-anywhere promise thereby inexorably evaporates.

Telling people that it's not a problem (or required!) to write non-well-formed 
XML, because a particular XML parser can't accept well-formed XML is kind of 
insidious.  I for one will not stand idly by and permit this outrage to remain 
unchallenged!!!

:)

Thank you that is good information, as that is kind of way that I am

So when you fetch the content from RSS, does that get rendered to an

Also what where a couple of decision points for using Solr as opposed

The filters and tokenizer that are applied to the copy field are

Re: Understanding prefix query searching

Hii,

You probably lower-case tokens during indexing (LowerCaseFilterFactory).  
Wildcard queries are not analyzed as non-wildcard ones (this is explained in 
Lucene FAQ, I believe), so your capitalized Robert doesn't match the 
lower-cased robert in your index.

Re: Out of Memory Errors

Hi,

Without knowing the details I suspect it's just that 1.5GB heap is not enough.  
Yes, sort will use your heap, as will various Solr caches.  As will norms, so 
double-check your schema to make sure you are using field types like string 
where you can, not text, for example.  If you sort by timestamp-like fields, 
reduce its granularity as much as possible.

Question about copyField


Hello.

I have field "description" in my schema. And I want make a filed
"suggestion" with the same content. So I added following line to my
schema.xml:

   

But I also want to modify "description" string before copying it to
"suggestion" field. I want to remove all comas, dots and slashes. Here
is an example of such transformation:

"TvPL/st, SAMSUNG, SML200"  => "TvPL st SAMSUNG SML200"

And so as result I want to have such doc:


 8asydauf9nbcngfaad
 TvPL/st, SAMSUNG, SML200
 TvPL st SAMSUNG SML200


I think it would be nice to use solr.PatternReplaceFilterFactory for
this purpose. So the question is: Can I use solr filters for
processing "description" string before copying it to "suggestion"
field?

Thank you for your attention.

Re: Index updates blocking readers: To Multicore or not?

Jim,

This is a off topic question.

But for your 30M documents, did you fetch those from external web
sites (Whole Web Search)? Or are they internal documents? If they
are external what method did you use to fetch them and which spider?

I am in the process of deciding between using Nutch for whole web
indexing, Solr + Spider?, or Nutch + Solr, etc.

Thank you in advance for your insight into this issue.

ways we can manage these "update burps".

Updates should never block queries.
What version of Solr are you using?
Is it possible that your indexes are so big, opening a new index in
the background causes enough of the old index to be flushed from OS
cache, causing big slowdowns?

-Yonik

Question #1: Anything obvious I can tweak in the configuration to
mitigate
these multi-second blocking updates? Our Indexes are 40GB, 20M
documents
each. RSync updates are every 5 minutes several hundred KB per
update.

Question #2: I'm considering setting up each slave with multiple
Solr

cores.
The 2 indexes per instance would be nearly identical copies but
"A" would

be
read from while "B" is being updated, then they would swap. I'll
have to
figure out how to rsync these 2 indexes properly but if I can get
the
commits to happen to the offline index then I suspect my queries
could

proceed unblocked.

Is this the wrong tree to be barking up? Any other thoughts?

Thanks in advance,

Jim

Re: Solr for Whole Web Search


Grant thanks for the response.

A couple of other people have recommended trying the Nutch + Solr  
approach, but I am not sure what the real benefit of doing that is.   
Since Nutch provides most of the same features as Solr and Solr has  
some nice additional features (like spell checking, incremental index).


So I currently have a Nutch Index of around 500,000+ Urls, but expect  
it to get much bigger.  And am generally pretty happy with it, but I  
just want to make sure that I am going down the correct path, for the  
best feature set.  As far as implementation to the front end is  
concerned, I have been using the Nutch search app as basically a  
webservice to feed the main app (So using RSS).  The main app takes  
that and manipulates the results for display.


As far as the Hadoop + Lucene integration, I haven't used that  
directly just the Hadoop integration with Nutch.  And of course Hadoop  
independently.

Re: Index updates blocking readers: To Multicore or not?

Thanks Yonik, 

I have more information...

1. We do indeed have large indexes: 40GB on disk, 30M documents - and is
just a test server we have 8 of these in parallel.

2. The performance problem I was seeing followed replication, and first
query on a new searcher.  It turns out we didn't configure index warming
queries very well so we removes the various "solr rocks" type queries to one
that was better for our data - and had not improvement.  The problem was
that replication completed, a new searcher was created and registered but
the first query qould take 10-20 seconds to complete.  There after it took
<200 milliseconds for similar non-cached queries.

Profiler pointed us to building the FieldSortedHitQueue was taking all the
time.  Our warming query did not include a sort but our queries commonly do. 
Once we added the sort parameter our warming query started taking the 10-20
seconds prior to registering the searcher.  After that the first query on
the new searcher took the expected 200ms.

LESSON LEARNED: warm your caches! And, if a sort is involved in your queries
incorporate that sort in your warming query!  Add a warming query for each
kind of sort that you expect to do.

Hi Sachit!

I've had the same problem with a search for whine. The origin of whine
can consist of up to three hierarchical values country (e.g.
"France"), region (e.g. "Bordeaux") and sub-region (e.g. "St.
Emilion").

I have three facet fields country, region, sub-region for that. But I
only display the "region" facet under the following conditions:

- the user has selected a specific country, e.g. France, as filter
- or only one country is left (due to other filtering or fulltext search)

Don't know if this suits you. Just the way I handle it. It's not yet
publicly available though.

Boosting Question

2008-10-22 Thread Manepalli, Kalyan

Hi,
I am working on a usecase where I want to boost a document if
there are certain group of words near the keywords searched by the user.

For eg: if the user is searching for keyword "pool", I want to boost the
documents which have words like "excellent pool", "nice pool", "awesome
pool", etc.

The list of words can be very large. 
Can anyone suggest an optimal solution to do this.

Thanks

FileNotFoundException on slave after replication - script bug?

We're seeing strange behavior on one of our slave nodes after replication.
When the new searcher is created we see FileNotFoundExceptions in the log
and the index is strangely invalid/corrupted.

We may have identified the root cause but wanted to run it by the community.
We figure there is a bug in the snappuller shell script, line 181:

snap_name=`ssh -o StrictHostKeyChecking=no ${master_host} "ls
${master_data_dir}|grep 'snapshot\.'|grep -v wip|sort -r|head -1"`

This line determines the directory name of the latest snapshot to download
to the slave from the master. Problem with this line is that it grab the
temporary work directory of a snapshot in progress. Those temporary
directories are prefixed with "temp" and as far as I can tell should never
get pulled from the master so its easy to disambiguate. It seems that this
temp directory, if it exists will be the newest one so if present it will be
the one replicated: FAIL.

We've tweaked the line to exclude any directories starting with "temp":
snap_name=`ssh -o StrictHostKeyChecking=no ${master_host} "ls
${master_data_dir}|grep 'snapshot\.'|grep -v wip|grep -v temp|sort -r|head
-1"`

This has fixed our local issue, we can submit a patch but wanted a quick
sanity check because I'm surprised its not much more commonly seen.

Re: Ocean realtime search + Solr

2008-10-22 Thread Jason Rutherglen

Not quite yet, there is the IndexReader.clone patch that needs to be
completed that Ocean depends on
https://issues.apache.org/jira/browse/LUCENE-1314.  I had it completed
but then things changed in IndexReader so now it doesn't work and I
have not had time to complete it again.  Otherwise the Ocean code
works, the issue is in how best to integrate with SOLR which is not
clear at this point given it requires a rather massive change in the
SolrCore tree of code (see
https://issues.apache.org/jira/browse/SOLR-567 for what changes are
needed).  Unfortunately it's not as simple as swapping out something
as the facet and field caching methodology needs to change.

RE: Out of Memory Errors

2008-10-22 Thread r.prieto

Hi Willie,

Are you using highliting ???

If, the response is yes, you need to know that for each document retrieved,
the solr highliting load into memory the full field who is using for this
functionality. If the field is too long, you have problems with memory.

You can solve the problem using this patch:

http://mail-archives.apache.org/mod_mbox/lucene-solr-dev/200806.mbox/%3C1552
[EMAIL PROTECTED]

to copy the content of the field who is used to highliting to another field
and reduce the size.

You also need to know too that Windows have a limitation for memory process
in 2 GB.

Asunto: Out of Memory Errors

Hello,

I've been having issues with out of memory errors on searches in Solr. I 
was wondering if I'm hitting a limit with solr or if I've configured 
something seriously wrong.

Solr Setup
- 3 cores 
- 3163615 documents each
- 10 GB size
- approx 10 fields
- document sizes vary from a few kb to a few MB
- no faceting is used however the search query can be fairly complex with 
8 or more fields being searched on at once

Environment:
- windows 2003
- 2.8 GHz zeon processor
- 1.5 GB memory assigned to solr
- Jetty 6 server

Once we get to around a few  concurrent users OOM start occuring and Jetty 
restarts.  Would this just be a case of more memory or are there certain 
configuration settings that need to be set?  We're using an out of the box 
Solr 1.3 beta version. 

A few of the things we considered that might help:
- Removing sorts on the result sets (result sets are approx 40,000 + 
documents)
- Reducing cache sizes such as the queryResultMaxDocsCached setting, 
document cache, queryResultCache, filterCache, etc

Am I missing anything else that should be looked at, or is it time to 
simply increase the memory/start looking at distributing the indexes?  Any 
help would be much appreciated.


Regards,

WW

Re: solr 1.3 database connection latin1/stored utf8 in mysql?

2008-10-22 Thread Jérôme Etévé

Hi,

  See
   http://java.sun.com/j2se/1.3/docs/guide/intl/encoding.doc.html
  and
   
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#getBytes(java.lang.String)

  Also note that you cannot transform a latin1 string in a utf-8
string. What you can do
is to decode a latin1 octet array to a String (java uses its own
internal representation for String which you shouldn't even know
about), and you can encode a String to an utf-8 bytes array.

Cheers.

Odd q.op=AND and fq interactions in Solr 1.3.0

2008-10-22 Thread jayson.minard


I am seeing odd behavior where a query such as:

http://localhost:8983/solr/select/?q=moss&version=2.2&start=0&rows=10&indent=on&fq=docType%3AFancy+Doc

works until I add q.op=AND

http://localhost:8983/solr/select/?q=moss&q.op=AND&version=2.2&start=0&rows=10&indent=on&fq=docType%3AFancy+Doc

which then causes 0 results.  There is only one term in the q parameter, and
the fq parameter I would think would be unaffected, and both of its terms
are there anyway although in a String field and not a tokenized way (so
maybe it is inserting an AND between Fancy AND Doc which isn't matching the
untokenized string anymore?)

Is there a way to apply q.op to q and not fq at the same time; if that is
indeed the problem?

Cheers!

Re: solr 1.3 database connection latin1/stored utf8 in mysql?


Hi Shalin 
Thanks for your answer but it doesn't work just with Dfile.encoding 
I was hoping it could work.

I definitely can't change the database so I guess I must change java code.
I've a function to change latin-1 string to utf8  but I don't know really
where should I put it?

Thanks for your answer,

before indexing ?

Thanks a lot for this information,

2008-10-22 Thread Shalin Shekhar Mangar

Hi,

The best way to manage international characters is to keep everything in
UTF-8. Otherwise it will be difficult to figure out the source of the
problem.

1. Make sure the program which writes data into MySQL is using UTF-8
2. Make sure the MySQL tables are using UTF-8.
3. Make sure MySQL client connections use UTF-8 by default
4. If the SQL written in your data-config has international characters,
start Solr with "-Dfile.encoding=UTF-8" as a command line parameter

http://dev.mysql.com/doc/refman/5.0/en/charset-connection.html

I don't think there is any easy way to go about this. You may need to
revisit all the parts of your system.

Re: error with delta import

Actually, most XML parsers don't require you to escape such characters in
attributes. You are welcome to try this out, just look at the example-DIH :)
