Subject [jira] [Commented] (LUCENE-4845) Add AnalyzingInfixSuggester
Date Mon, 15 Jul 2013 14:12:49 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13708484#comment-13708484

Shai Erera commented on LUCENE-4845:
------------------------------------

Mike, will you still commit it to 4.4? I think that the branch was created prematurely as
there's still no resolution on whether to release or not. And this feature is pretty isolated
to cause any instability ... it'd be a petty to have to wait with releasing it another 3-4
months just because of technicalities...

> Our current suggester impls do prefix matching of the incoming text
> against all compiled suggestions, but in some cases it's useful to
> allow infix matching.  E.g, Netflix does infix suggestions in their
> search box.
> I did a straightforward impl, just using a normal Lucene index, and
> using PostingsHighlighter to highlight matching tokens in the
> suggestions.
> I think this likely only works well when your suggestions have a
> strong prior ranking (weight input to build), eg Netflix knows
> the popularity of movies.
