Isn't this what Solr/Lucene are designed to do?? On indexing a document, Lucene creates an inverted index, mapping terms back to their containing documents. The data you have is already inverted.
I'd suggest uninverting it and then hand it to Solr in that format, thus: doc1: java doc2: java doc4: book doc5: java doc9: book doc77: book With that structure, you'll have in your index exactly what Solr expects, and will be able to take advantage of the inbuilt ranking capabilities of Lucene and Solr.
