Question: How to query programmatically

[reckart]

The code we are currently using in INCEpTION to perform an MTAS search looks pretty complicated - but I am pretty sure that is the way we were told that querying MTAS would work:

    private static void doQuery(IndexReader indexReader, String field, MtasSpanQuery q,
            List<String> prefixes)
        throws IOException
    {
        ListIterator<LeafReaderContext> iterator = indexReader.leaves().listIterator();
        IndexSearcher searcher = new IndexSearcher(indexReader);
        final float boost = 0;
        SpanWeight spanweight = q.rewrite(indexReader).createWeight(searcher, false, boost);

        while (iterator.hasNext()) {
            LeafReaderContext lrc = iterator.next();
            Spans spans = spanweight.getSpans(lrc, SpanWeight.Postings.POSITIONS);
            SegmentReader segmentReader = (SegmentReader) lrc.reader();
            Terms terms = segmentReader.terms(field);
            CodecInfo mtasCodecInfo = CodecInfo.getCodecInfoFromTerms(terms);
            if (spans != null) {
                while (spans.nextDoc() != Spans.NO_MORE_DOCS) {
                ...

But normally, querying lucene would use something like searcher.query(q, myCollector) - and there are also search signatures which would e.g. allow for sorting results etc. So I was wondering (I haven't tried it yet): can the search/collector approach really not be used with MTAS? If not, why? And if it can be used, does anybody have an example for it?
