sort by function problem

[ramzesua <mi...@gmail.com>]

I try to use sort by function in a new release of SOLR 3.1, but I have some
problems, for example:
http://localhost:8983/new_search/select?q=mothers
day&indent=true&fl=templateSetId,score,templateSetPopularity&sort=product(templateSetPopularity,query(mothers
day)) desc
templateSetPopularity - my field with popularity rank
query(mothers+day,0.0) - I try to get score value
At result I get error:
HTTP Status 400 - Can't determine Sort Order:
'sum(templateSetPopularity,query(mothers day)) desc', pos=3
Where is my error?

The problem is "query(mothers day)"
See http://wiki.apache.org/solr/FunctionQuery#query

You can't directly include query syntax because the function parser
wouldn't know how to get to the end of that syntax.
You could either do
   "query($qq)"  and then add a "qq=mothers day" to the request
Or if you really wanted the whole thing inline, you could do
   "query({!v='mothers day'})

But the first form is nicer since you don't have to worry about
escaping at all, and I think it's also more readable.
