---------------------------------------
Summary: Error on reindex using WordNet synonyms file
Key: LUCENE-8100
URL: https://issues.apache.org/jira/browse/LUCENE-8100
Project: Lucene - Core
Issue Type: Bug
Components: modules/analysis
Affects Versions: 7.0.1
Reporter: Mayya Sharipova
Priority: Minor
Originally reported in the ES issues:
https://github.com/elastic/elasticsearch/issues/27798#issuecomment-351838983
but looks like the issue is introduced from the Lucene 7.0.X.
Copying the user's issue here:
------------------------------------------------------
I'm encountering the following error on indexing when trying to use the wn_s.pl
synonyms file (which I've moved to /usr/local/etc/elasticsearch):
{code:javascript}
{
"error": {
"root_cause": [{
"type": "illegal_argument_exception",
"reason": "failed to build synonyms"
}],
"type": "illegal_argument_exception",
"reason": "failed to build synonyms",
"caused_by": {
"type": "parse_exception",
"reason": "Invalid synonym rule at line 2",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "term: physical entity analyzed to a
token with posinc != 1"
}
}
}
}
{code}
Here's the line it's objecting to:
s(100001930,1,'physical entity',n,1,0).
I'm using the WordNet Prolog synonyms file from
http://wordnetcode.princeton.edu/3.0/WNprolog-3.0.tar.gz2
------------------------------------------------------
Looks like the error comes from Lucene's classes of *WordnetSynonymParser* and
*SynonymMap*, and changes introduce from Lucene 7.0 version.
