Custom scorer...
Is there a way to specify a custom scorer in Solr using the XML configuration
file ? I want to
use the AND operator (e.g. "Lucene AND Solr") to search multiple fields and
then add the
similarity score for each field using a custom similiarity computation for
each.
Thanks.

Hmm, have you checked out DisjunctionSumQuery from lucene? I think it
might be close to what you are looking for.

Yonik,
I have my own Similarity and now need to write my own Scorer for muti
field scoring.
Is extending DisMaxQueryScorer the way to go ?
Thanks.

If you created your own Similarity implementation, then just specify
it in the schema.xml.
If you created your own Scorer, then that's a whole different
matter... you need to create a custom query handler to use it (start
with standard or dismax).

I haven't written any unfortunately. Right now, I have only implemented
custom Similarity - in here, I am trying to alter the scoring substantially
depending on the field. However, I might need to alter the overall
document score - I am in the process of investigating if I can get away
without having write custom code beyond tweaking just the Similarity class.

: specify similarity. There was nothing for scoring - in case I need to modify
: the
: scoring. I got the similarity working by creating my own class.
customer Scorer classes are really only possible via custom Query and
Weight classes -- which are typically way beyond what most people need to
modify to achieve their goals. What kind of Query/Weight/Scorer have you
written?

Yonik,
I only saw options to specify the default operator (AND|OR) and to
specify similarity. There was nothing for scoring - in case I need to modify
the
scoring. I got the similarity working by creating my own class.
Thanks.

Both of these are in the schema... look through the provided example schema.xml
