I haven’t found anything on Google except that ICUCollationKeyAnalyzer
depends on the icu4j library, which I verified is part of the SOLR
package.
The icu4j library and the related Lucene jars for ICU capability are not
part of Solr by default. They can be found in the "contrib" in the Solr
download ... but you must add the jars to Solr if you intend to use any
contrib capability.
The best way I have found to add custom jars to Solr is to create a
"lib" directory under the location designated as the solr home and place
the jars there. All jars found in that directory will be automatically
loaded and will be available to all cores.
An alternate way to load jars is with the <lib> directive in
solrconfig.xml ... but I don't recommend that approach.
Thanks,
Shawn
