Subject [jira] Commented: (LUCENE-2295) Create a MaxFieldLengthAnalyzer to wrap any other Analyzer and provide the same functionality as MaxFieldLength provided on IndexWriter
Date Sat, 06 Mar 2010 14:16:28 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842263#action_12842263
] 

Robert Muir commented on LUCENE-2295:
-------------------------------------

Add this to the list of potential future checks in BaseTokenStreamTestcase.

Perhaps we can use this new limiting analyzerwrapper in assertAnalyzesToReuse
to help determine if tokenstreams implement reset() correctly, versus just assuming
the entire stream will be consumed completely.

> A spinoff from LUCENE-2294. Instead of asking the user to specify on IndexWriter his
requested MFL limit, we can get rid of this setting entirely by providing an Analyzer which
will wrap any other Analyzer and its TokenStream with a TokenFilter that keeps track of the
number of tokens produced and stop when the limit has reached.
> This will remove any count tracking in IW's indexing, which is done even if I specified
UNLIMITED for MFL.
> Let's try to do it for 3.1.
