Subject [jira] Commented: (LUCENE-2295) Create a MaxFieldLengthAnalyzer to wrap any other Analyzer and provide the same functionality as MaxFieldLength provided on IndexWriter
Date Fri, 05 Mar 2010 14:18:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12841877#action_12841877
] 

Uwe Schindler commented on LUCENE-2295:
---------------------------------------

In the indexer, the backwards code is hairy: If a max limit is set, the indexer just plugs
our Filter around the TokenStream. This would limit nr. of tokens for all cases:

# An ANALYZED field (wrapping the TokenStream got from Analyzer)
# A Field with ctor taking TokenStream: wrap the Field's TokenStream

We need some cache here, too :( -- The analyzer cannot be used because of (2).

> 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.
