Something along the following should work and be quite fast. However, it
might be overly complex.
// Do this every time the index is updated
IndexReader reader = IndexReader.open(indexLocation);
BitSet deleted = new BitSet(reader.maxDoc());
for (int i = 0 ; i < reader.maxDoc() ; i++) {
if (reader.isDeleted(i)) {
deleted.set(i);
}
}
QueryParser parser =
new QueryParser("freetext", new StandardAnalyzer());
// Do this for every search
Query query = parser.parse("java");
QueryWrapperFilter filter = new QueryWrapperFilter(query);
BitSet workset = filter.bits(reader);
workset.or(deleted);
// workset now marks all docids that are either matching or deleted
System.out.print("Non-matching documents: ");
for (int i = 0 ; i < reader.maxDoc() ; i++) {
if (!workset.get(i)) {
System.out.print(i + " ");
}
}
