Query regarding solr plugin.
One doubt regarding adding the solr plugin.
I have a new java file created that includes few changes in
SynonymFilterFactory.java. I want this java file to be added to solr
instance.
I created a package as : org.apache.pco.search
This includes OrcSynonymFilterFactory java class extends
BaseTokenFilterFactory implements ResourceLoaderAware {code.....}
Packages included: import org.apache.solr.analysis.*;
import org.apache.lucene.analysis.Token;
import org.apache.lucene.analysis.TokenStream;
import org.apache.solr.common.ResourceLoader;
import org.apache.solr.common.util.StrUtils;
import org.apache.solr.util.plugin.ResourceLoaderAware;
import java.io.File;
import java.io.IOException;
import java.io.Reader;
import java.io.StringReader;
import java.util.ArrayList;
import java.util.List;
I exported this java file in eclipse,
selecting File tab-Export to package
-org.apache.pco.search-OrchSynonymFilterFactory.java
and generated jar file - org.apache.pco.orchSynonymFilterFactory.jar
This jar file placed in /lib folder of solr home instance
Changes in solr config - <lib dir="./lib" />
Now i want to add this in schema fieldtype for synonym filter as
<filter class="org.apache.pco.search.orchSynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
But i am not able to do it.." It has an error
as org.apache.solr.common.SolrException: Error loading class
'pointcross.orchSynonymFilterFactory' at
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:373)
at
org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:388)
at org.apache.solr.util.plugin.AbstractPluginLoader"
Please can anyone tell me , What is the mistake i am doing here and the fix
for it ?

Erick,
Thank you. I could fix the problem. Started from scratch considering your
advice and been successful. Thanks a lot.

Re: Query regarding solr plugin.
Posted by Erick Erickson <er...@gmail.com>.
Sorry, but there's too much here to debug remotely. I strongly advise you
back waaaay up. Undo (but save) all your changes. Start by doing
the simplest thing you can, just get a dummy class in place and
get it called. Perhaps create a really dumb logger method that
opens a text file, writes a message, and closes the file. Inefficient
I know, but this is just to find out the problem. Debugging by println is
an ancient technique...
Once you're certain the dummy class is called, gradually build it up
to the complex class you eventually want.
One problem here is that you've changed a bunch of moving parts, copied
jars around (it's unclear whether you have two copies of solr-core in your
classpath, for instance). So knowing exactly which one of those is the issue
is very difficult, especially since you may have forgotten one of the things
you did. I know when I've been trying to do something for days, lots of
details get lost.
Try to avoid changing the underlying Solr code, can you do what you want
by subclassing instead and calling your new class? That would avoid
a bunch of problems. If you can't subclass, copy the whole thing and
rename it to something new and call *that* rather than re-use the
synonymfilterfactory. The only jar you should copy to the <lib> directory
would be the one you put your new class in.
I can't emphasize strongly enough that you'll save yourself lots of grief if
you start with a fresh install and build up gradually rather than try to
unravel the current code. It feels wasteful, but winds up being faster in
my experience...
Good Luck!
Erick

Re: Query regarding solr plugin.
Posted by rajini maski <ra...@gmail.com>.
Thanks Erick. I have added my replies to the points you did mention. I am
somewhere going wrong. I guess do I need to club both the jars or something
? If yes, how do i do that? I have no much idea about java and jar files.
Please guide me here.
A couple of things to try.
1> when you do a 'jar -tfv <yourjar>", you should see
output like:
1183 Sun Jun 06 01:31:14 EDT 2010
org/apache/lucene/analysis/sinks/TokenTypeSinkTokenizer.class
and your <filter> statement may need the whole path, in this example...
<filter class="org.apache.lucene.analysis.sinks.TokenTypeSink"..../> (note,
this
is just an example of the pathing, this class has nothing to do with
your filter)...
I could see this output..
2> But I'm guessing your path is actually OK, because I'd expect to be
seeing a
"class not found" error. So my guess is that your class depends on
other jars that
aren't packaged up in your jar and if you find which ones they are and copy
them
to your lib directory you'll be OK. Or your code is throwing an error
on load. Or
something like that...
There is jar - "apache-solr-core-1.4.1.jar" this has the
BaseTokenFilterFacotry class and the Synonymfilterfactory class..I made the
changes in second class file and created it as new. Now i created a jar of
that java file and placed this in solr home/lib and also placed
"apache-solr-core-1.4.1.jar" file in lib folder of solr home. [solr home -
c:\orch\search\solr lib path - c:\orch\search\solr\lib]
3> to try to understand what's up, I'd back up a step. Make a really
stupid class
that doesn't do anything except derive from BaseTokenFilterFacotry and see
if
you can load that. If you can, then your process is OK and you need to
find out what classes your new filter depend on. If you still can't, then we
can
see what else we can come up with..
I am perhaps doing same. In the synonymfilterfactory class, there is a
function parse rules which takes delimiters as one of the input parameter.
Here i changed comma ',' to '~' tilde symbol and thats it.

Rajani

Re: Query regarding solr plugin.
Posted by Erick Erickson <er...@gmail.com>.
Looking at things more carefully, it may be one of your dependent classes
that's not being found.
A couple of things to try.
1> when you do a 'jar -tfv <yourjar>", you should see
output like:
1183 Sun Jun 06 01:31:14 EDT 2010
org/apache/lucene/analysis/sinks/TokenTypeSinkTokenizer.class
and your <filter> statement may need the whole path, in this example...
<filter class="org.apache.lucene.analysis.sinks.TokenTypeSink"..../> (note, this
is just an example of the pathing, this class has nothing to do with
your filter)...
2> But I'm guessing your path is actually OK, because I'd expect to be seeing a
"class not found" error. So my guess is that your class depends on
other jars that
aren't packaged up in your jar and if you find which ones they are and copy them
to your lib directory you'll be OK. Or your code is throwing an error
on load. Or
something like that...
3> to try to understand what's up, I'd back up a step. Make a really
stupid class
that doesn't do anything except derive from BaseTokenFilterFacotry and see if
you can load that. If you can, then your process is OK and you need to
find out what classes your new filter depend on. If you still can't, then we can
see what else we can come up with..

Erick ,

* Thanks.* It was actually a copy mistake. Anyways i did a redo of all the
below mentioned steps. I had given class name as
<filter class="pointcross.orchSynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
I did it again now following few different steps following this link :
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.jdt.doc.user/tasks/tasks-32.htm
1 ) Created new package in src folder . *org.apache.pointcross.synonym*.This
is having class Synonym.java
2) Now did a right click on same package and selected export option->Java
tab->JAR File->Selected the path for package -> finish
3) This created jar file in specified location. Now followed in cmd , jar
tfv
org.apache.pointcross.synonym. the following was desc in cmd.
:\Apps\Rajani Eclipse\Solr141_jar>jar -
tfv org.apache.pointcross.synonym.Synonym.jar

1017 Thu Apr 21 16:34:20 GMT+05:30 2011 jarLog.jardesc
4) Now placed same jar file in solr home/lib folder .Solrconfig.xml
enabled <lib dir="./lib" /> and in schema <filter class="synonym.Synonym"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
5) Restart tomcat : http://localhost:8097/finding1

Re: Query regarding solr plugin.
Posted by Erick Erickson <er...@gmail.com>.
First I appreciate your writeup of the problem, it's very helpful when people
take the time to put in the details....
I can't reconcile these two things:
{{{<filter class="org.apache.pco.search.orchSynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
as org.apache.solr.common.SolrException: Error loading class
'pointcross.orchSynonymFilterFactory' at}}}
This seems to indicate that your config file is really looking for
"pointcross.orchSynonymFilterFactory" rather than
"org.apache....pco.search.orchSynonymFilterFactory".
Do you perhaps have another definition in your config
"pointcross.orchSynonymFilterFactory"?
Try running "jar -tfv <your jar file>" to see what classes
are actually defined in the file in the solr lib directory. Perhaps
it's not what you expect (Perhaps Eclipse did something
unexpected).
Given the anomaly above (the error reported doesn't correspond to
the class you defined) I'd also look to see if you have any old
jars lying around that you somehow get to first.
Finally, is there any chance that your "pointcross.orchSynonymFilterFactory"
is a dependency of "org.apache....pco.search.orchSynonymFilterFactory"? In
which case Solr may be finding
"org.apache....pco.search.orchSynonymFilterFactory"
but failing to load a dependency (that would have to be put in the lib
or the jar).
Hope that helps

Hi,
Maybe you are doing query-time synonym expansion?
Try changing that to do index-time synonym expansion.

Multi-word Solr Synonym issue
Posted by Pla Gong <pg...@marketlive.com>.
I am trying to do a simple mapping of a 2 word term to a 1 word term and
it does not work. See my configuration at the bottom of the email. My
scenario is that I have a term called "pond care" and I want to map it
to the term "fountain". So whenever a user enters the term "pond care"
in the search box, I want Solr to search on the word "fountain".
Searching on "fountain" or "pond food" should returns the same number
of products. I try all type of filter combination and cannot get it to
work. I use the Solr analysis and "pond food" does map to "fountain"
but when test on Solr Admin, the search would not query on "fountain"
but only on "pond care". Here is my log from solr Admin search:
- <lst name="debug">
- <lst name="queryBoosting">
<str name="q">fountain</str>
<null name="match" />
</lst>
<str name="rawquerystring">pond food</str>
<str name="querystring">pond food</str>
<str name="parsedquery">+text:pond +text:food</str>
<str name="parsedquery_toString">+text:pond +text:food</str>
- <lst name="explain">
<str name="catalogItem.155.120.1">1.4865229 = (MATCH) sum of:
0.5013988 = (MATCH) weight(text:pond in 1137), product of: 0.5317582 =
queryWeight(text:pond), product of: 3.180518 = idf(docFreq=730,
maxDocs=6470) 0.16719232 = queryNorm
I am new to Solr and I have Google the issue but I did not find a
solution that will work for my case. Please let me know if you have
encounter this issue and how you resolved it and what configuration you
used. I want term to term mapping results from the query and not a
combination of the two terms.
I would greatly appreciate any help.
Thanks,
Pla
