solr: multiply score with a field

Hopefully an easy question: I have added some docs to the index, where every doc has a field prio, which is an integer between 1 and 5. There is also a text field for fulltext search.

What I want: multiply the prio-value with the score value and order the docs by tha开发者_StackOverflowt result.

what I tried: this and that :) last thing was q=whatever _val_:"product(prio, score)" which didn't work (unknown field score)

Thanks for your help!

How about:

q={!boost b=field(prio)}whatever
