Hi The problem I would like to solve is determining the lucene score of a word in _a particular_ given document. The 2 candidates i have been trying are
- QueryWrapperFilter - BooleanQuery Both are to restrict search within a search space. But according to Doug Cutting QueryWrapperFilter option is less preferable than Boolean Query. However, I am experiencing both performance (very slow) and response problems (query is not matched to any doc). The setup is as follows. Given a user query "word": QueryParser parser = new QueryParser(Version.LUCENE_32, "content",new StandardAnalyzer(Version.LUCENE_32)); Query query = parser.parse(word); Document d = WikiIndexSearcher.doc(match.doc); docTitle = d.get("title"); TermQuery titleQuery = new TermQuery(new Term("title", docTitle)); BooleanQuery bQuery = new BooleanQuery(); bQuery.add(titleQuery, BooleanClause.Occur.MUST); bQuery.add(query, BooleanClause.Occur.MUST); TopDocs hits = WikiIndexSearcher.search(bQuery, 1); In other words, find a wikipedia doc with a particular title (in example below it is "list of newspapers in New York http://en.wikipedia.org/wiki/List_of_newspapers_in_New_York"). We then create a boolean term query with that must match on the title and content must match the user query ('american' in the example below). Here is the output of a run on user query "american" in a doc with title "list of newspapers in New York"). ... QUERY: content:american ... doc: List of newspapers in New York ... query: +title:List of newspapers in New York +content:american ... explanation 568744: 0.0 = (NON-MATCH) Failure to meet condition(s) of required/prohibited clause(s) 0.0 = no match on required clause (title:List of newspapers in New York) 0.011818626 = (MATCH) weight(content:american in 212081), product of: 0.15625292 = queryWeight(content:american), product of: 2.4204094 = idf(docFreq=392249, maxDocs=1623450) 0.0645564 = queryNorm 0.075637795 = (MATCH) fieldWeight(content:american in 212081), product of: 1.0 = tf(termFreq(content:american)=1) 2.4204094 = idf(docFreq=392249, maxDocs=1623450) 0.03125 = fieldNorm(field=content, doc=212081) As you can see there is no match to the query (and hits.totalcounts is 0). The search is very slow too. Any help would be much appreciated
