Still can not implement this feature. Previously to perform a search in the 'label', I used the following code that worked:
Query q = new QueryParser(Version.LUCENE_43, "label", analyzer > ).parse(label); > searcher.search(q, collector); > ScoreDoc[] hits = collector.topDocs().scoreDocs; But with BooleanQuery does not work. What I want is the result of those TopDocs, do the search but in the 'abstract' to filter. Has anyone implemented something similar? 2013/8/7 Ian Lea <ian....@gmail.com> > Your BooleanQuery code looks fine. Do the label and abstract searches > work independently?
