3) Is there a plan for adding QueryParser support for the SpanQuery family?
Another important facet to Terry's question here is what syntax to use to express all various types of queries? I suspect that Google stats
And others - Altavista logs I think...
show us that most folks query with 1 - 3 words and do not use the any of the advanced features.
But with automagic query expansion these things might be done behind the scenes. Nutch, for one, expands simple queries to check against multiple fields, with different boosts, and even gives a bonus for terms that are near each other.
The elegance of the query syntax is quite important, and QueryParser has gotten a bit hairy. I would enjoy discussions on creating new query parsers (one size doesn't fit all, I don't think) and what syntax
I suggested in some email a while ago making the QueryParser extensible at, runtime or startup time, so you can add other types if queries that it doesn't support - so you have a way of registering these other query types (SpanQuery, SubstringQuery etc) and then some syntax like "span:foo" to invoke the query expander registered w/ "span" on "foo"...
should be used.
Paul Elschot created a "surround" query parser that he posted about to the list in April.
