Summary: Fix CachingTokenFilter to propagate reset() the first time
Key: LUCENE-6121
URL: https://issues.apache.org/jira/browse/LUCENE-6121
Project: Lucene - Core
Issue Type: Improvement
Reporter: David Smiley
Assignee: David Smiley
Fix For: 5.0, Trunk
CachingTokenFilter should have been propagating reset() _but only the first
time_ and thus you would then use CachingTokenFilter in a more normal way –
wrap it and call reset() then increment in a loop, etc., instead of knowing you
need to reset() on what it wraps but not this token filter itself. That's
weird. It's ab-normal for a TokenFilter to never propagate reset, so every user
of CachingTokenFilter to date has worked around this by calling reset() on the
underlying input instead of the final wrapping token filter (CachingTokenFilter
in this case).
