I am running some complicated span near searches and the results do not
make much sense.
Take the following toy example:
{'span_near': {'clauses': [
{'span_term': {'text': 'foo'}},
{'span_near': {'clauses': [{'span_term':
{'text': 'biz'}},
{'span_term':
{'text': 'buz'}}],
'in_order': False,
'slop': 0}}],
'in_order': False,
'slop': 0}}
I would *expect* that this search would return documents where foo, biz,
and buz were directly next to each other. I would expect it to match:
foo biz buz
I would *not expect* it to match:
foo biz and biz buz
However, nested span_near queries seem to match both documents. I have a
feeling this is an issue with Lucene rather than ES, but does anyone know
whether this was done by design? It seems like an entirely
counter-intuitive result.
