Re: Incomplete documents with parent child DB relationship

[Mikhail Khludnev]

Hello,

IIRC, DIH UI has some kind of verbose or debug option, which provides
expanded trace of what's going on. Can't you try to check it?

Re: Using multiple DirectSolrSpellcheckers for a query

[Nalini Kartha]

Hi James/Robert,

Thanks for the responses.

Robert: What is it about the current APIs that makes this hard? How
much/what kind of refactoring would open this up?

James: I didn't quite understand the usage you suggested. I thought that
the spellcheck.q param shouldn't include field names, etc and that the
purpose of specifying this param is to avoid the extra parsing out of the
field names, etc. from the q param to get the query terms for spell
checking. This is based on this bit in the SpellCheckComponent wiki -

" The spellcheck.q parameter is intended to be the original query, minus
any extra markup like field names, boosts, etc."

Did I misunderstand something?

I agree that it's impossible to know if the query "run" should be corrected
to "sun" or "running" in the example I gave but I guess I'm asking more
from the angle of how to avoid correcting terms that will be matched
because they exist in other more processed fields that are being searched.
Since the recommendation is to build spellcheck fields from minimally
processed source fields, seems like this would be a common problem?

And another kind of unrelated question - all the examples of spellcheck
dictionaries I've seen in sample solrconfig.xmls have minPrefix set to 1.
Is this for performance reasons? And with this setting, we wouldn't get
"run" as a correction for "eon" right?

Thanks,
Nalini

Consider using SolrJ, possibly combined with
Tika (which is what underlies Solr Cel).
http://www.lucidimagination.com/blog/2012/02/14/indexing-with-solrj/

AlthoughExtractingRequestHandler
has the capability of indexing metadata as
well if you map the fields.

What exactly do you mean by that? Why is integration with Solr
a requirement, and what do you expect to gain by such an integration?
"Best" also probably depends on the context of your requirements.

There are a variety of open-source recommendation engines.
If you are looking at something from Apache, and in Java, Mahout
might be a good choice.

Highlighting a font without bold or italic modes

[Lance Norskog]

How do you highlight terms in languages without boldface or italic
modes? Maybe raise the text size a couple of sizes just for that word?

Can solr-langid(Solr3.5.0) detect multiple languages in one text?

[bing]

Hi, all, 

I am using solr-langid(Solr3.5.0) to do language detection, and I hope
multiple languages in one text can be detected. 

The example text is: 
咖哩起源於印度。印度民間傳說咖哩是佛祖釋迦牟尼所創，由於咖哩的辛辣與香味可以幫助遮掩羊肉的腥騷，此舉即為用以幫助不吃豬肉與牛肉的印度人。在泰米爾語中，「kari」是「醬」的意思。在馬來西亞，kari也稱dal（當在mamak檔）。早期印度被蒙古人所建立的莫臥兒帝國（Mughal
Empire）所統治過，其間從波斯（現今的伊朗）帶來的飲食習慣，從而影響印度人的烹調風格直到現今。
Curry (plural, Curries) is a generic term primarily employed in Western
culture to denote a wide variety of dishes originating in Indian, Pakistani,
Bangladeshi, Sri Lankan, Thai or other Southeast Asian cuisines. Their
common feature is the incorporation of more or less complex combinations of
spices and herbs, usually (but not invariably) including fresh or dried hot
capsicum peppers, commonly called "chili" or "cayenne" peppers.

I want the text can be separated into two parts, and the part in Chinese
goes to "text_zh-tw" while the other one "text_en". Can I do something like
that? 

Thank you. 

Best Regards, 
Bing

Incomplete documents with parent child DB relationship

[Tim Hurring]

I'm new to SOLR and have managed to get some basic indexing and querying
working. However I haven't been able to successfully implement the indexing
of a parent child database relationship.

My db-data-config.xml is:




   
  
  
  
  
  
  

  




Most 'client' records will have one or more 'idreference' records. SOLR
seems to import the data successfully (see status below) but when I do a *:*
search there are no 'id_reference' elements in any document (see below at
bottom):



0

Re: Display of highlighted search result should start with the beginning of the sentence that contains the search string.

[Koorosh Vakhshoori]

Hi Koji,
  I am Shyam's coworker. After some looking into this issue, I believe the
problem of chopped word has to do with
org.apache.lucene.search.vectorhighlight.SimpleFragListBuilder class'
'margin' field. It is set to 6 by default. My understanding is having margin
value of greater than zero results in truncated word when the highlighted
term is too close to beginning of a document. I was able to reset the
'margin' field by creating my custom version of
org.apache.solr.highlight.SimpleFragListBuilder and passing zero for
'margin' when calling the Lucene's SimpleFragListBuilder constructor. My
testing shows the problem has been fixed. Do you concur?

  Now couple of questions. Not sure what the purpose of this field is, could
you give the use case for it? Also could it be exposed as a parameter in
Solr so it could be set to some other value?

Thanks,

Koorosh

query to some field in solr for multiple values

[preetesh dubey]

How can we perform query to single string type field for multiple values?
e.g.
I have the schema field like



I want to query on id field for multiple values like..

"q=id:['1', '5', '17']..."

in mysql we perform the same query like..

"select * from table where id in(1,5,17) "

how can we perform the same query in solr on id field?

RE: Including an attribute value from a higher level entity when using DIH to index an XML file

[Mike O'Leary]

I found an answer to my question, but it comes with a cost. With an XML file 
like this (this is simplified to remove extraneous elements and attributes):


  
[message text]
...
  
  ...


I can index the user id as a field in documents that represent each of the 
user's messages with this data-config expression:


  
  

  
  
  
   
  


I didn't realize that commonField would work for cases in which the previously 
encountered field is in an element that encompasses the other elements, but it 
does. The forEach value has to be "/data/user/message | /data/user" in order 
for the user id to be located, since it is not under /data/user/message.

By specifying forEach="/data/user/message | /data/user" I am saying that each 
/data/user or /data/user/message element is a document in the index, but I 
don't really want /data/user elements to be treated this way. As luck would 
have it, those documents are filtered out, only because date and text are 
required fields, and they have not been assigned values yet when a document is 
created for a /data/user element, so an exception is thrown. I could live with 
this, but it's kind of ugly.

I don't see any other way of doing what I need to do with embedded XML elements 
though. I tried creating nested entities in the data-config file, but each one 
of them is required to have a url attribute, and I think that caused the input 
file to be read twice.

The only other possibility I could see from reading the DataImportHandler 
documentation was to specify an XSL file and change the XML file's structure so 
that the user id attribute is moved down to be an attribute of the message 
element. I'm not sure it's worth it to do something like that for what seems 
like a small problem, and I wonder how much it would slow down the importing of 
a large XML file.

Are there any other ways of handling cases like this, where an attribute of an 
outer element is to be included in an index document that corresponds to an 
element nested inside it?
Thanks,
Mike

Subject: Including an attribute value from a higher level entity when using DIH

I have an XML file that I would like to index, that has a structure similar to 
this:


  
[message text]
...
  
  ...


I would like to have the documents in the index correspond to the messages in 
the xml file, and have the user's [id-num] value stored as a field in each of 
the user's documents. I think this means that I have to define an entity for 
message that looks like this:


  
  

  
  
   
  


but I don't know where to put the field definition for the user id. It would 
look like



I can't put it within the message entity, because it is defined with 
forEach="/data/user/message/" and the id field's xpath value is outside of the 
entity's scope. Putting the id field definition there causes a null pointer 
exception. I don't think I want to create a "user" entity that the "message" 
entity is nested inside of, or is there a way to do that and still have the 
index documents correspond to messages from the file? Are there one or more 
attributes or values of attribute that I haven't run across in my searching 
that provide a way to do what I need to do?
Thanks,
Mike

Sort by bayesian function for 5 star rating

[Zac Smith]

Does anyone have an example formula that can be used to sort by a 5 star rating 
in SOLR?
I am looking at an example on IMDB's top 250 movie list: 

The formula for calculating the Top Rated 250 Titles gives a true Bayesian 
estimate:
 weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C 
where:
R = average for the movie (mean) = (Rating)
v = number of votes for the movie = (votes)
m = minimum votes required to be listed in the Top 250 (currently 3000)
C = the mean vote across the whole report (currently 6.9)

Solr Monitoring / Stats

[Alex Leonhardt]

Hi All,

I was wondering if anyone knows of a free tool to use to monitor 
multiple Solr hosts under one roof ? I found some non functioning cacti 
& munin trial implementation but would really like more direct 
statistics of the JVM itself + all Solr cores (i.e. requests /s , etc.) ?


Does anyone know of one ? Or has a set of JMX URLs that could be used to 
make i.e. munin or cacti use that data ?


I'm currently running psi-probe on each host to have at least some 
overview of whats going on within the JVM.



Thanks!
Alex

Re: Trouble indexing word documents

Make sure the Solr cell jar is in the classpath. You probably have a line

Relational data

[André Maldonado]

Hi.

I need to setup an index that have relational data. This index will be for
houses to rent, where the user will search for date, price, holydays (by
name), etc.

The problem is that the same house can have different prices for different
dates.

If I denormalyze this data, I will show the same house multiple times in
the resultset, and I don't want this.

So, for example:

House  Holyday   Price per day
1  Xmas  $ 75.00
1  July 4  $ 50.00
1  Valentine's   $ 15.00
2  Xmas   $ 50.00
2  July 4  $ 10.00

If I query for all data, I'll get 3 documents for the same house (house 1),
but I just want to show it one time to the end-user.

There is some way to do this in Solr (Without processing it in my app)?

Thank's

RE: solr 3.5 and indexing performance

[Agnieszka Kukałowicz]

Hi guys,

I have hit the same problem with Hunspell.
Doing a few tests for 500 000 documents, I've got:

Hunspell from http://code.google.com/p/lucene-hunspell/ with 3.4 version -
125 documents per second
Build Hunspell from 4.0 trunk - 11 documents per second.

All the tests were made on 8 core CPU with 32 GB RAM and index on SSD
disks.
For Solr 3.5 I've tried to change JVM heap size, rambuffersize,
mergefactor but the speed of indexing was about 10 -20 documents per
second.

Is it possible that there is some performance bug with Solr 4.0? According
to previous post the problem exists in 3.5 version.

Best regards
Agnieszka Kukałowicz

AW: Performance (responsetime) on request

Hi,

thanks for you advice. Do you have any documentation on that? I'm not sure, how 
and where to configure this stuff and what impact it has.

Re: How to index doc file in solr?

[Erick Erickson]

Consider using SolrJ, possibly combined with
Tika (which is what underlies Solr Cel).
http://www.lucidimagination.com/blog/2012/02/14/indexing-with-solrj/

AlthoughExtractingRequestHandler
has the capability of indexing metadata as
well if you map the fields.

See: http://wiki.apache.org/solr/ExtractingRequestHandler

Re: 3 Way Solr Join . . ?

[Erick Erickson]

I know it goes against the grain here for a DB
person, but... denormalize. Really. Solr does
many things well, but whenever you start
trying to make it do database-like stuff you need
to back up and re-think things.

Simplest thing: Try indexing one record
for each customer/purchase/complaint
triplet. How many records are we talking here
anyway? 30-40M documents will probably
perform admirably on even a small piece
of hardware.

Re: Strange behavior with search on empty string and NOT

[Erick Erickson]

Because Lucene query syntax is not a strict Boolean logic system.
There's a good explanation here:
http://www.lucidimagination.com/blog/2011/12/28/why-not-and-or-and-not/

Adding &debugQuery=on to your search is your friend .. You'll see
that your return (at least on 3.5 with going at /solr/select) returns
this as the parsed query:

-name:foobar

Solr really doesn't have the semantics for empty strings (or NULL for
that matter) so it just gets dropped out.

If you look at solr admin page / statistics of cache, you could check the 
evictions of different types of cache. If some of them are larger than zero, 
try minimizing them by increasing the corresponding cache params in the 
solrconfig.xml.

Re: Faster Solr Indexing

[Erick Erickson]

How have you determined that it's the solr add? By timing the call on the
SolrJ side or by looking at the machine where Solr is running? This is the
very first thing you have to answer. You can get a rough ides with any
simple profiler (say Activity Monitor no a Mac, Task Manager on a Windows
box). The point is just to see whether the indexer machine is being
well utilized. I'd guess it's not actually.

One quick experiment would be to try using StreamingUpdateSolrServer
(SUSS), which has the capability of having multiple threads
fire at Solr at once. It is possible that your performance is spent
waiting for I/O.

Once you have that question answered, you can refine. But until you
know which side of the wire the problem is on, you're flying blind.

Both Yandong Peyman:
These times are quite surprising. Running everything locally on my laptop,
I'm indexing between 5-7K documents/second. The source is
the Wikipedia dump.

I'm particularly surprised by the difference Yandong is seeing based
on the various analysis chains. the first thing I'd back off is the
MaxPermSize. 512M is huge for this parameter.
If you're getting that kind of time differential and your CPU isn't
pegged, you're probably swapping in which case you need
to give the processes more memory. I'd just take the MaxPermSize
out completely as a start.

Not sure if you've seen this page, something there might help.
http://wiki.apache.org/lucene-java/ImproveIndexingSpeed

But throw a profiler at the indexer as a first step, just to see
where the problem is, CPU or I/O.

What exactly do you mean by that? Why is integration with Solr
a requirement, and what do you expect to gain by such an integration?
"Best" also probably depends on the context of your requirements.

There are a variety of open-source recommendation engines.
If you are looking at something from Apache, and in Java, Mahout
might be a good choice.

If you check lucene/BUILD.txt in your source, it says to use ant 1.7.1 
or later, but not 1.8.x.  This is from a recent trunk checkout:


Basic steps:
  0) Install JDK 1.6 (or greater), Ant 1.7.1+ (not 1.6.x, not 1.8.x)
  1) Download Lucene from Apache and unpack it
  2) Connect to the top-level of your Lucene installation
  3) Install JavaCC (optional)
  4) Run ant
Ok, thanks. Didnt catch that. Have another checkout of solrtrunk from 
about 2 weeks ago, where I didnt see the problem?!?!?!? In that I am 
able to run "ant test" etc. without license problems.


A previous message on the mailing list about the missing license 
messages (from 2012-02-23) says that some work has been done to get it 
working with ant 1.8, but it's not done yet.  Can you downgrade or 
install the older release in an alternate location?

Im sure I will manage, now that I know what the problem is. Thanks again.


It looks like ant 1.8 has been out for two years, so newer operating 
systems are going to be shipping with it and it may become difficult 
to get the older ant release.  I know from my own systems that 
CentOS/RHEL 6 is still using ant 1.7.1.

Re: Performance (responsetime) on request

[Dmitry Kan]

If you look at solr admin page / statistics of cache, you could check the
evictions of different types of cache. If some of them are larger than
zero, try minimizing them by increasing the corresponding cache params in
the solrconfig.xml.

Yes it is possible. Two different approaches are described in a recent thread. 
http://search-lucene.com/m/Wicj8UB0gl2

One of them uses both trailing and leading wildcard, e.g. q=*TARCSV*

Other approach makes use of NGramFilterFactry at index time only.

It seems that you will be dealing with extremely long tokens. It is a good idea 
to increase maxTokenLength (default value is 255)
SOLR-2188 Tokens longer than this are silently ignored.

Re: SOLR Query Intersection

[Mikhail Khludnev]

It sounds like facets http://wiki.apache.org/solr/SolrFacetingOverview .
Doesn't it?

SOLR Query Intersection

[balaji]

Hi , 

   I am trying to Compare three independent queries,intersection among them
and draw an Venn diagram using the Google CHART .  By using OR I will be
able to get the union of the 3 fields and using AND I will be able to get
the intersection among the three , Is it possible to get the union and
intersection among the fields in a  same query 

For ex :

I have 3 values which is under Multi-valued field browsers  "Google ,
Firefox and IE "  . I just need to find the no.of documents having only
google , Firefox etc.. and no.of documents having all the three and an
intersection among them like "Google & IE"  , "Google & Firefox"

   Is it possible to do with the Query Intersections or do I need to write
separate queries for all the above , If not please suggest how it can be
achieved


Thanks
Balaji

Performance (responsetime) on request

[Ramo Karahasan]

Hi,

 

i've got two virtual machines in the same subnet at the same
hostingprovider. On one machine my webapplication is running, on the second
a solr instance. In solr I use the following













 





















 

 





  

  

  



 

 

 

 

If I search from my webapplication in my autosuggest box, I get response
times of ~500ms per request. Is it possible to "tune" solr, so that I get
faster results?

I have no special cache configuration, nor I don't know what to configure
here.

 

Thanks,

Ramo
