I worked out a new version of the swish-e org indexer that indexes custom xml representing the org file that you may find interesting for your project.
http://kitchingroup.cheme.cmu.edu/blog/2015/07/04/An-xml-representation-of-an-org-document-for-indexing-with-swish-e/ It enables a search like this: swish-e -f index-org2xml.swish-e -w src-block.language=python -w src-block=diffusion to find org files with a python source block containing the word diffusion. I think swish-e supports ranking (http://swish-e.org/docs/swish-faq.html#how_is_ranking_calculated_) too, but I have not tried it. It is pretty interesting overall!
