Hello,
I am running a Perl site and I am evaluating Solr as a gateway to Lucene. So
far I am very pleased with the functionality it provides and the performance.
My Java is quite basic so I am sorry if my questions sound trivial but I am
trying to configure Solr to index a Russian site and I am hitting some hurdles.
I have a basic install using the Jetty bundle from the tutorial.
Firstly I have added the following to schema.xml:
<fieldtype name="textRussian" class="solr.TextField"
positionIncrementGap="100" >
<analyzer class="org.apache.lucene.analysis.ru.RussianAnalyzer"/>
</fieldtype>
And then added a Russian field:
<field name="name" type="textRussian" indexed="true" stored="true"/>
I downloaded lucene-analyzers-2.0.0.jar and placed it in the lib directory
(tried both solr/lib and solr/example/lib) but I keep getting the same error
(ClassNotFoundException, see stack trace below) when starting the server. Have
I missed a step here??
I have been through the mailing list archive and haven’t found a definite
answer to my question above. I have also investigated the next step which is
the ability to add stop words, synonyms etc. It seems that I will have to
create my own Factory(ies?) but didn’t find a detailed explanation on how to do
this. I found this useful:
http://www.mail-archive.com/solr-user@lucene.apache.org/msg00198.html but a
bit too high-level for me! Should this be included in the Wiki?
Many thanks
Stephanie
