Subject [jira] [Commented] (LUCENE-4822) Add PatternKeywordTokenFilter to marks keywords based on regular expressions
Date Mon, 11 Mar 2013 12:49:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13598780#comment-13598780

Uwe Schindler commented on LUCENE-4822:
---------------------------------------

In addition: CharArraySet allows to do "contains(CharSequence)", so we dont need to pass the
array directly. contains(termAtt) is enough to check for existence in the set.

If you dont want to remove the parameter of isKeyword, make it CharSequence.

> today we need to pass in an explicit set of terms that we want to marks as keywords.
It might make sense to allow patterns as well to prevent certain suffixes etc. to be keyworded.
