Re: Implement custom score

[Erik Hatcher]

Actually what William should use is the new Sort facility to order  
results by a field.  Doing this with a Similarity would be much  
trickier.  Look at the IndexSearcher.sort() methods which take a Sort  
and follow the Javadocs from there.  Let us know if you have any  
questions on sorting.

It would be best if you represent your 'popularity' field as an integer  
(or at least numeric) since sorting by String uses more memory.

Hi,
I know this is probably a common question and I've found a couple of
posts
about it in the archive but none with a complete answer. If there is
one
please point me to it!
The question is that I want to discard the default scoring and
implement my
own. I want all the the hits to be sorted after popularity (a field)
and
not by anything else. How can I do this? What classes and methods do
I have
to change?
thanks,
William
