[jira] Commented: (LUCENE-1095) StopFilter should have option to

-------------------------------------
>From <http://mail-archives.apache.org/mod_mbox/lucene-java-user/200510.mbox/%3c435D44FA.6050702@syr.edu%3e>:
A patch implementing this approach was actually applied to
StopFilter.java in late 2003, but was reverted shortly afterward,
because this approach conflicts with the QueryParser and PhraseQuery
implementations.
See Doug Cutting's description of the problem with the position
increment modification approach here:
<http://mail-archives.apache.org/mod_mbox/lucene-java-dev/200312.mbox/%3c3FCFB3CA.9000103@lucene.com%3e>
See a colored diff of StopFilter.java, just before and after the
position increment modification patch was reverted, here:
<http://svn.apache.org/viewcvs.cgi/lucene/java/trunk/src/java/org/apache/lucene/analysis/StopFilter.java?rev=150152&r1=150150&r2=150152&diff_format=h>

> StopFilter should have an option that if set, records how many stop words are "skipped" in a row, and then sets that value as the positionIncrement on the "next" token that StopFilter does return.
