What you probably want to achieve is displaying only docs in a certain
category (maybe filtered) ordered by descending score in the context of
exactly this category, right?
Well, you could come over this by creating a category specific score
field for every category following the schema "cat-X-score" where X is
the identifier of each of your categories. Then when receiving a request
for your category you programmatically have to build the sort-by
condition for field "cat-Y-score", where Y is the category id of the
category you received the request for.

Hi Otis,
thanks for the reply,
consider a multivalued field name cat
<doc>
--other fields
<field name=cat> val 1 <field name="catrank> score1 </field> </field>
<field name=cat> val 2 <field name="catrank> score2 </field> </field>
<field name=cat> val 3 <field name="catrank> score3 </field> </field>
......
--other fields
<doc>
the query i have to use is
q= cat:query-text; sort catrank desc
get all the documents
WITH field cat HAVING query-text
AND order by catrank desc

Umar,
I'm not sure what you mean by a "subfield", can you explain please?
As for your second question, just add category:X to your query and you'll
get matches ordered/ranked by score by default.

Subject: ranking on Multivalued fields
Hi,
I have a problem where i want to rank multivalued fields
suppose a multivalued field "category" having associated subfield "score".
First Is it possible to have a subfield in the mutlivalued field?
Second I want to get the documents ranked with the highest score say for
the
category:X
thanks
