Subject [jira] [Updated] (LUCENE-4822) Add PatternKeywordTokenFilter to marks keywords based on regular expressions
Date Mon, 11 Mar 2013 13:09:13 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4822?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Uwe Schindler updated LUCENE-4822:
----------------------------------

    Attachment: LUCENE-4822.patch

small change for safety: explicitely cast the termAttribute to CharSequence to be sure, the
right (and most effective method) is called in CharArraySet. Otherwise it might happen that
contains(Object) is called.

> 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.
