Solr boost score based on wikipedia PageRank and solr score

I have solr indexed wikipedia dump. I get the results from solr query which have results shown according to the lucene score.

In the indexed files from Wikipedia i also have the field: PageRank calculated based on the inbound links to the title.

I want to get more relevant results based on the lucene score and the PageRank field.

What should be my approach here?.
How can i boost the results based on both the values.

Appreciate any leads.

If you are using the standard query parser or extended dismax, you can use this query

q=[your query]+AND+_val_:"PageRank"

Using both regular document score AND custom score based on the value of a field is the default behavior when you use the SolR FunctionQuery with the \_val\_ hook.
