Migration Lucene 3=>4: IndexSearcher.setDefaultFieldSortScoring(..)

[Christian Reuschling]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

We currently migrate one project to Lucene 4 and noticed that the method
IndexSearcher.setDefaultFieldSortScoring(..) disappeared in Lucene 4.0. We 
can't find something
about this in the migration guide. Further, it was never deprecated in Lucene 
3, so we didn't find
related documentation on it. Also didn't find something in the mailing list.

Is it save to just leave it out? We use and display scores also if the result 
list was sorted by
field value, so we set the field sort scoring to true in any case in the past. 
How can we achieve
this now?


best

Hi Christian,

I found an entry about this in the 4.0-ALPHA “Changes in backwards 
compatibility policy” section of Lucene’s CHANGES.txt (html version): 
:

LUCENE-3514: IndexSearcher.setDefaultFieldSortScoring was removed
and replaced with per-search control via new expert search methods
that take two booleans indicating whether hit scores and max score
should be computed. (Mike McCandless) 

See:
