How to boost a solr document at query time based on attribute value

I want boost at query time all documents that have value user_id=2. Basically I want on the top of my results all the documents belonged to a specific user. After looking at some Solr resources I ended up writing a query like, but it is not working properly.

/solr/public-main/select?q={!boost b=if(div(155623,user_id),2,1)}sometext&wt=json&indent=true&debugQuery=true

Any hints?

Thanks

One option is to have a function query with fl=x,y,userexists:exists(query({!v='user_id:2'})) and then u can sort by userexists and then by score field.

You don't need to use the boost with a dynamic boost. Apply a boost query which will boost all the documents that match the query: bq=user_id:2^4. Adjust 4 to a suitable boost value depending on the rest of your boosts (if any in q or qf).
