Hello, Chris Morley here, of Wayfair.com. I am working on the German
compound-splitter by Dawid Weiss.
I tried to "upgrade" the words.fst file that comes with the German
compound-splitter using Solr 3.5, but it doesn't work. Below is the
IndexNotFoundException that I get.
cmorley@Caracal01:~/Work/oss/git/apache-solr-3.5.0$ java -cp
lucene/build/lucene-core-3.5-SNAPSHOT.jar org.apache.lucene.index.IndexUpgrader
wordsFst
Exception in thread "main" org.apache.lucene.index.IndexNotFoundException:
org.apache.lucene.store.MMapDirectory@/home/cmorley/Work/oss/git/apache-solr-3.5.0/wordsFst
lockFactory=org.apache.lucene.store.NativeFSLockFactory@201a755e
at
org.apache.lucene.index.IndexUpgrader.upgrade(IndexUpgrader.java:118)
at
org.apache.lucene.index.IndexUpgrader.main(IndexUpgrader.java:85)
The reason I'm attempting this at all is due to the answer here,
http://stackoverflow.com/questions/25450865/migrate-solr-1-4-index-files-to-4-7,
which says to do the upgrade in a two step process, first using Solr 3.5, and
then the latest Solr version (4.10.3). When I try this running the unit tests
for my modified German compound-splitter I'm getting this same type of error.
The thing is, this is an FST, not an index, which is a little confusing. The
reason why I'm following this answer though, is because I'm getting that exact
same message when trying to build the (modified) project with maven....at the
point at which it tries to load in words.fst. Below.
[main] ERROR com.wayfair.lucene.analysis.de.compound.GermanCompoundSplitter -
Format version is not supported (resource:
com.wayfair.lucene.analysis.de.compound.InputStreamDataInput@79a66240): 0
(needs to be between 3 and 4). This version of Lucene only supports indexes
created with release 3.0 and later. Failed to initialize static data
structures for German compound splitter.
Thanks,
-Chris.
