Re: Solrcloud dataimport failed at first time after restart

[jun Wang]

I have found the reason.  The reason is that I am using jboss JNDI
datasource, and oracle driver is placed in WEB-INFO/lib, this is a very
common error, driver should be placed in %JBOSS_HOME%\server\default\lib.

Re: Query foreign language "synonyms" / words of equivalent meaning?

[Bernd Fehling]

As far as I know, there is no built-in functionality for language translation.
I would propose to write one, but there are many many pitfalls.
If you want to translate from one language to another you might have to
know the "starting" language. Otherwise you get problems with translation.

Not (german) -> distress (english), affliction (english)

- you might have words in one language which are stopwords in other language 
"not"
- you don't have a one to one mapping, it's more like "1 to n+x"
  toilette (french) -> bathroom, rest room / restroom, powder room

This are just two points which jump into my mind but there are tons of pitfalls.

We use the solution of a multilingual thesaurus as synonym dictionary.
http://en.wikipedia.org/wiki/Eurovoc
It holds translations of 22 official languages of the European Union.

So a search for "europäischer währungsfonds" gives also results with
"european monetary fund", "fonds monétaire européen", ...

Bernd

Have had very minimal experience with Bluehost, as we are hosted
mostly from EC2. The main difference is that with Bluehost shared
hosting---at least our version of it---one has access only to their pre-
built software stacks, and cannot install arbitrary applications. It is
possible that Bluehost has other offerings that enable one to do so,
but in the absence of that, Solr on Bluehost would not be possible.

Re: SolrJ 4.0 Beta maxConnectionsPerHost

[Briggs Thompson]

Thanks all for your responses. For some reason the emails were getting
filtered out of my inbox.

*Otis* - jstack is a great suggestion, thanks! The problem didn't happen
this morning but next time it does I will certainly get the dump to see
exactly where the app is swimming around. I haven't used
StreamingUpdateSolrServer
but I will see if that makes a difference. Are there any major drawbacks of
going this route?

*Sami* - if you are referring to
config:maxConnections=200&maxConnectionsPerHost=8,
it showed up up in the Solr logs, not the SolrJ logs. The client IS
instantiated only once and not for every request. I was curious if this was
part of the problem. Do I need to re-instantiate the object for each
request made? I figured there would be more overhead if I am re-creating
the connection several times when I never really need to shut it down, but
at this point the overhead would be minimal though so I will try that.

*Hoss* - The reason it seemed the client was creating the log was because
the indexer (solr *server*) was more or less dormant for several hours,
then I booted up my indexing *client* and the maxConnectionsPerHost tidbit
was spit out right away. I was looking for something in the solrconfig and
online but didn't find anything. I didn't look for very long so will check
it out again.

Some very good suggestions here. I appreciate everyones feedback. I will
follow up after some experimentation.

Thanks,
Briggs Thompson

PostFilters, Grouping, Sorting Oh My!

[Amit Nithian]

Hi all,

I've been working with using Solr's post filters/delegate collectors
to collect some statistics about the scores of all the documents and
had a few questions with regards to this when combined with grouping
and sorting:
1) I noticed that if I don't include the "score" field as part of the
sort spec with *no* grouping enabled, my custom delegate scorer gets
called so I can then collect the stats I need. Same is true with score
as part of the sort spec (this then leads me to focus on the grouping
feature)
2) If I turn ON grouping:
  a) WITH "score" in the sort spec, my custom delegate scorer gets called
  b) WITHOUT "score" in the sort spec, my custom delegate scorer does
NOT get called.

What's interesting though is that there *are* scores generated so I'm
not sure what all is going on. I traced through the code and saw that
the scorer gets called as part of one of the comparators
(RelevanceComparator) which is why with "score" in the sort spec it
works but that is about as far as I could go. Since I am not too
worried in my application about a sort spec without the score always
being there it's not a huge concern; however, I do want to understand
why with the grouping feature enabled, this doesn't work and whether
or not it's a bug.

Any help on this would be appreciated so that my solution to this
problem is complete.

Thanks!
Amit

Re: Auto Correction?

[Amit Nithian]

What's preventing you from using the spell checker and take the #1
result and re-issue the query from a sub-class of the query component?
It should be reasonably fast to re-execute the query from the server
side since you are already within Solr. You can modify the response to
indicate that the new query was used so your client can display to the
user that it searched automatically for "milky.. click here for
searches for mlky" or something.

To elaborate on sami's comment...

If you are seeing this in the logs from your solr *server*, it is unlikey 
that it has anything to do with the settings you are making on your solr 
*client*  this is probably related to the http client created inside 
solr for communicating with other solr nodes (ie: replication, solr cloud

from the properties you set on the http client in your solr client

I believe there is a way to configure the defaults for the internal used

Re: SolrJ Apidoc - is there any comprehensive literature ?

[Erick Erickson]

The "javadocs" link here: http://lucene.apache.org/solr/index.html
takes you to the API documentation...

if you go to the frames view and click on org.apache.client.solrj in the
upper left you'll see the solrj classes only

I'll often get the source and execute "ant documentation" to get
a local copy of all the javadocs. If you open
/solr/build/docs/index.html you get a nice top-level
local HTML page.

Other than that, you're really best off looking over some of the
code examples on the web. The javadocs can be kind of sparse
as well, any clarifications you'd like to contribute as patches would
be very welcome! There's often great value in someone seeing
the docs with fresh eyes...

Off-topic, but this is because the Unicode escape sequence
'\u' is not being interpreted here. You have to explicitly
do that. Here is an example with '\u2018', the opening

Re: Installing Solr on a shared hosting server?

[Michael Della Bitta]

Bluehost doesn't seem to support Java processes, so unfortunately the
answer seems to be no.

You might want to look into getting a Linode or some other similar VPS
hosting. Solr needs RAM to function well, though, so you're not going
to be able to go with the cheapest option.

Installing Solr on a shared hosting server?

[caiod]

I was wondering if I can install Solr on bluehost's shared hosting to use as
a website search, and also how do I do so? Thank you...

Re: How to use complicated boolean query?

[Jack Krupansky]

You also do the full query with one level of BooleanQuery by using the 
BooleanQuery#setMinimumNumberShouldMatch(int min) method. The default 
minimum number of optional clauses to match is zero, but you can set it to 1 
for your case. I don't know if there is any difference in performance or 
scoring between these two approaches.


Using Solr, it's the "mm" request parameter.

I want to implement a query in Solr like the follow
((X OR Y) AND Z) … ((X ∨ Y) ∧ Z)
BooleanQuery q = new BooleanQuery();
BooleanQuery inner = new BooleanQuery();
inner.add(X, Occur.SHOULD);
inner.add(Y, Occur.SHOULD);
q.add(inner, Occur.MUST);
q.add(Z, Occur.MUST);

For example, I want to query
(Field1=X or Field1=Y ) and Field2=Z

Re: SolrJ 4.0 Beta maxConnectionsPerHost

[balaji.gandhi]

Hi Briggs,

Did you try StreamingUpdateSolrServer? We are still facing the same issues
but noticed this happens only when "Physical Memory" in Solr Admin is high.
And yes SolrJ respects the connections.

Hi Team,

Another option we discussed was upgrading to HttpClient 4.2 in Solr war.
Would that fix the issue?

Thanks,
Balaji

Re: Anyone using mmseg analyzer in solr multi core?

[Peter Keegan]

We're using MMSeg with Lucene, but not Solr. Since each SolrCore is
independent, I'm not sure how you can avoid each having a copy of the
dictionary, unless you modified MMSeg to use shared memory. Or, maybe I
missing something.

Re: Help with Velocity in SolrItas

[Erik Hatcher]

As Paul mentioned, printing the class name helps tremendously.  The $response 
(SolrQueryResponse) can contain all sorts of nested objects of various types, 
so it's necessary to know what kind of object it is (generally, but not alway) 
to be able to navigate it effectively.

A shortcut, you can actually use $sentence.class

Velocity leverages naming conventions and treats things like "beans" even if 
they technically aren't, so if it has a getFoo() method, $object.foo will work 
to retrieve the value.  

I'm curious what kind of object you have for $sentence.  Often you'll get a 
NamedList, which has a get(Object) method.  Likewise with a HashMap.   

You may be able to get away with using $sentence.index and $sentence.text.  
Knowing the object type will point you to everything you can call on it.  And 
Velocity's documentation is here: 

 (geeky and maybe slightly tricky at first, but fairly straightforward once you 
know what object types you're dealing with)

RE: Indexing in Solr: invalid UTF-8

[Patrick Oliver Glauner]

Hello everybody

Meanwhile, I checked this issue in detail: we use pdftotext to extract text 
from our PDFs (). Some generated text files contain \u 
and \uD835.

unicode(text, 'utf-8') does not throw any exception for these texts. 
Subsequently, Solr throws an exception when these are sent to the indexer.

Therefore, I wrote a little function to remove them after the unicode() call:
+def remove_invalid_solr_characters(utext):
+for char in CFG_SOLR_INVALID_CHAR_REPLACEMENTS:
+try:
+utext = utext.replace(char, 
CFG_SOLR_INVALID_CHAR_REPLACEMENTS[char])
+except:
+pass
+return utext

with:
+CFG_SOLR_INVALID_CHAR_REPLACEMENTS = {
+u'\u' : u"",
+u'\uD835' : u""
+}

This works well in our production environment.

Cheers, Patrick

Python's unicode function takes an optional (keyword) "errors"
argument, telling it what to do when an invalid UTF8 byte sequence is
seen.

The default (errors='strict') is to throw the exceptions you're
seeing.  But you can also pass errors='replace' or errors='ignore'.

See http://docs.python.org/howto/unicode.html for details ...

However, I agree with Robert: you should dig into why whatever process
you used to extract the full text from your binary documents is
producing invalid UTF-8 ... something is wrong with that process.

Re: Wildcards and fuzzy/phonetic query

[Erick Erickson]

It won't crash Solr if you include it, but it probably won't do what
you expect either due to how wildcards are expanded.

And it gets worse. DoubleMetaphone tries to reduce what it
analyzes, well, phonetically with "close" letters (or multiple
choices). Some phonetic filters change to fixed 4 letter
combinations as I remember. Some hash to a completely different
string. Some

About combining fuzzy and wildcard. I haven't thought it through,
but it strikes me as fraught with unexpected results. Consider
har* and treating it as a fuzzy match. How would you calculate
the "fuzziness" of "hardiness" and "harp"? Would you consider
"her" a fuzzy match? How about "farther"? or even "father"?

You might be able to do something interesting with EdgeNgram
here though but it still seems like it's going to either explode
computationally or produce results that don't really mean much.
But I'm mostly speculating here

Frankly, though, I'd do what Jan suggests. Try it out and see if
it's "good enough". Especially pin down the use cases. Often
requirements like this are specified by someone who, when
presented with the results of what you can do easily, decide the
effort could best be spent somewhere else.

Because this whole approach will only increase the number of
documents that are found as the result of a search without
necessarily increasing the relevance of the top N docs on the
first page. Users rarely go to the second page, and often don't
even look past the first few results. Doing wildcard AND fuzzy
queries would likely result in something useful  a very small
percentage of the time. But that's just a guess.

Re: Wildcards and fuzzy/phonetic query

[Jan Høydahl]

Hi,

Also be sure to check out the new BeiderMorse phonetic: 
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.BeiderMorseFilterFactory
 which handles middle eastern and eastern european names very well.

Phonetic algorithms use tons of rules for how to transform an input depending 
on what comes before and after, so I don't believe you'll get wildcard to work 
perfectly combined with phoenetic since Solr cannot guess what shuould come 
next. But you may get it to work for many cases, the best is simply to try it 
out. Use EdgeNgram followed by some phonetic ant try.

You may also be interested in a MeetUp talk held in Oslo last month: 
http://www.meetup.com/Oslo-Solr-Community/events/67253692/ You'll find the link 
to Mats' talk about Norwegian phonetics if you scroll down that page.

SolrJ Apidoc - is there any comprehensive literature ?

[tomtom]

Hi,

is there a comprehensive documentation of the SolrJ Api?  The given
resources are hard to read and have only few information. The Guide from
lucid imagination gave me a certain progress but is just a well organized
compilation of the apache documents. For programming there's just few help
and the apidoc seems very spare.   

I wonder where the gracefully given hints in this forum (and others) are
from. Is it really necessarey to inspect the source-code of Solr? Does
anyone knows about "readable" and nearly complete documentation? 

A sometimes frustrated Solr-User/programmer.

Thank you in advance, tom

impossible or functionally doesn't make sense? :)  

I wrote in an answer to Otis that I'd like to try to combine fuzzy with Ngram 
as well.  Do you know if that is possible and makes any sense?


Thanks to everyone for quick and good answers, I really appreciate it!

Auto Correction?

[deniz]

Hi all,

I would like to ask if there are any ways to correct user's queries
automatically? I know there is spellchecker which *suggests* possible
correct words... The thing i wanna do is *automatically fixing* those
queries and running instead of the original one

for example
if our query is "mlky", it should automatically search for "milky"

there is synonyms filter for these, but it has to be pre populated (correct
me if i am wrong)  so it wont be that useful for my case...

is there any way to do this without suggesting-only and synonym filters? if
so please give me some details

Re: How to use complicated boolean query?

[Alexandre Rafalovitch]

And the problem is? I think it is just brackets. E.g.
Field1:(X Y) AND Field2:Z

No?
