Subject [jira] [Commented] (LUCENE-3792) Remove StringField
Date Thu, 16 Feb 2012 19:19:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209630#comment-13209630

Hoss Man commented on LUCENE-3792:
----------------------------------

StrawMan suggestion off the top of my head:

* rename NOT_ANALYZED to something like KEYWORD_ANALYZED
* document KEYWORD_ANALYZED as being a convenience flag (and/or optimization?) for achieving
equivalent behavior as using PerFieldAnalyzer with KeywordAnalyzer for this field, and keep
using / re-word rmuir's patch warning to make it clear that if you use this at index time,
any attempts to construct queries against it using the QueryParser will need KeywordAnalyzer.

...would that flag name == analyzer name equivalence help people remember not to get trapped
by this?

> Often on the mailing list there is confusion about NOT_ANALYZED.
> Besides being useless (Just use KeywordAnalyzer instead), people trip up on this
> not being consistent at query time (you really need to configure KeywordAnalyzer for
the field 
> on your PerFieldAnalyzerWrapper so it will do the same thing at query time... oh wait
> once you've done that, you dont need NOT_ANALYZED).
> So I think StringField is a trap too for the same reasons, just under a 
> different name, lets remove it.
