[jira] [Reopened] (JCR-3428) Partial search terms are no longer highlighted in the excerpts

["Alex Parvulescu (JIRA)" <ji...@apache.org>]

Alex Parvulescu reopened JCR-3428:
----------------------------------


The fix can't be backported to the 2.4 branch - the tests don't pass.
Most likely this is a change in the lucene apis.

There are 2 options now:

 #1: the trunk keeps the rewrite behavior to CONSTANT_SCORE_BOOLEAN_QUERY_REWRITE and the 2.4 branch switches to SCORING_BOOLEAN_QUERY_REWRITE so the excerpt tests pass

OR

 #2: both use the SCORING_BOOLEAN_QUERY_REWRITE even thought it is not considered the best option in all the cases:
{{Note that typically such scores are meaningless to the user, and require non-trivial CPU to compute, so it's almost always better to use CONSTANT_SCORE_AUTO_REWRITE_DEFAULT instead.}} [0]

My vote is with keeping things consistent: #2

> It seems that the highlighting behavior has changed after the lucene 3.0.3 upgrade.
> This slipped unnoticed until now, and it affects the current code (using lucene 3.6) as well.
> Before for partial search terms the highlighter would highlight the entire matching term, now it fails to do so.
> Example, for the content: {{lorem ipsum dolor sit amet}} searching for {{ipsu*}} would have to highlight the entire matching term {{ipsum}}, and currently it does not.
