Class org.apache.lucene.index.IndexReader

Examples of org.apache.lucene.index.IndexReader.termDocs()

org.apache.lucene.index.IndexReader.termDocs()
Returns an enumeration of all the documents which contain term. For each document, the document number, the frequency of the term in that document is also provided, for use in search scoring. If term is null, then all non-deleted docs are returned with freq=1. Thus, this method implements the mapping:
The enumeration is ordered by document number. Each document number is greater than all that precede it in the enumeration. @throws IOException if there is a low-level IO error

            throws IOException {
        IndexReader reader = index.getIndexReader();
        try {
            checkRewritten(reader);
            Term idTerm = new Term(FieldNames.UUID, id.getUUID().toString());
            TermDocs tDocs = reader.termDocs(idTerm);
            int docNumber;
            Document doc;
            try {
                if (tDocs.next()) {
                    docNumber = tDocs.doc();
