Paul,
Thanks for pointing me to the surround code. I have started playing
with it, and am impressed. Now I just need to adjust my thinking a bit
more to see if I can implement the tool correctly, and get my specific
search functionality out of what it offers.
You've been a great help,
Sean

Hello,
I am trying to do some complex queries such as:
[Field contents]
The movie Napoleon Dynamite is a movie about a kid named Napoleon who
has no Dynamite.
[Query]
"Napol* Dynamite" near "film|movie"
Is this possible with some version of a span query? Something like a
PhrasePrefixQuery joined to a BooleanQuery by a SpanNearQuery?
This can be done using nested SpanNearQuery's and SpanOrQuery's.
A PhrasePrefixQuery can not be used as a SpanQuery.
If not, does anyone have a suggestion on how to do this? I am
assuming I will need to do two queries, and determine the 'nearness' of
the resulting hits myself.
Thanks,
You can do this using the surround query language:
(Napol* w dynamite) n (film or movie)
The surround parser will construct the nested span queries.
The surround query language is in the contrib/surround directory
in the development version. The most striking difference with
the lucene standard query language is that all operators
have to be given explicitly, there is no implicit 'and' or 'or'.
