Thank you Bernd! I couldn't make it run though. Here is my problem:
1. There is a file ~/apache-solr-1.4.1/ifaq/lib/stempel-1.0.jar
2. In ~/apache-solr-1.4.1/ifaq/solr/conf/solrconfig.xml there is a
directive: <lib path="../lib/stempel-1.0.jar" />
3. In ~/apache-solr-1.4.1/ifaq/solr/conf/schema.xml there is fieldType:
(...)
<!-- Polish -->
<fieldType name="text_pl" class="solr.TextField">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="org.getopt.stempel.lucene.StempelFilter" />
<!-- <filter
class="org.getopt.solr.analysis.StempelTokenFilterFactory"
protected="protwords.txt" /> -->
</analyzer>
</fieldType>
(...)
4. jar file is loaded but I got an error:
SEVERE: Could not start SOLR. Check solr/home property
java.lang.NoClassDefFoundError: org/apache/lucene/analysis/TokenFilter
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:634)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
(...)
5. Different class gave me that one:
SEVERE: org.apache.solr.common.SolrException: Error loading class
'org.getopt.solr.analysis.StempelTokenFilterFactory'
at
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:375)
at
org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:390)
(...)
Question is: How to make <fieldType /> and <filter /> work with that Stempel? :)
Cheers,
Jakub Godawa.
