Artem Lukanin created LUCENE-5051:
-------------------------------------
Summary: Incorrect abbreviation synonyms treating in
WordDelimiterFilter
Key: LUCENE-5051
URL: https://issues.apache.org/jira/browse/LUCENE-5051
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 4.3, 4.3.1
Reporter: Artem Lukanin
If there are 2 abbreviation synonyms in the stream, they are not treated as
synonyms after splitting by dots in WordDelimiterFilter.
Correct treatment:
before and after WordDelimiterFilter:
<code><pre>
tokens: wi fi wireles network
positions: 1 2 1 2
</pre></code>
Incorrect treatment:
before WordDelimiterFilter:
<code><pre>
tokens: wi.fi. wireles.network.
positions: 1 1
</pre></code>
after WordDelimiterFilter:
<code><pre>
tokens: wi fi wireles network
positions: 1 2 3 4
</pre></code>
but should be:
<code><pre>
tokens: wi fi wireles network
positions: 1 2 1 2
</pre></code>
See a patch for Solr 4.3.1 configs, which demonstrates the bug if "wi.fi.
router" is analyzed in name_syn field.
