Hi, I am trying to retrieve Terms for a given set of documents (int array or Bitset), which is the result of a query.
// Index creation // Query with an IndexSearcher IndexSearcher searcher = new IndexSearcher(ir); TopDocs docs = searcher.search(query, 100); >From the "docs", an array of int can be extracted which represents a set of document resulting from the query. From this set, I need a way to get terms frequency for this set only. I have identified a solution by storing terms vectors during index creation, using a FieldType with "type.setStoreTermVectors(true);" And then requesting for each document of the set the stored terms vector (with Terms acting like a "single-document inverted index"): Terms docterms = ir.getTermVector(docs.scoreDocs[0].doc, "contents"); // Terms of a document However, I would have to then merge the Terms of each document forming the set, which is not a pleasant solution. Is there a way by using only the lucene API to request the Terms for a given sub-set of document present in the index ?
