Proximity searching and phrase

[Lucene <Lu...@roylip.ftech.net>]

Hi,

I was wondering is there is a way to do proximity searches with phrases
eg "very good" NEAR "sometimes".

Any help on this would be welcome.

Many thanks,


Roy

You can do this with the new SpanQuery family in v1.4.  The example you 
gave would consist of a SpanTermQuery for "very", "good", and 
"sometimes", with the first two combined with a SpanNearQuery (with no 
slop, in order), and finally the "very good" SpanNearQuery combined 
with another SpanNearQuery with the "sometimes" SpanTermQuery.  *whew* 
:)

There is no QueryParser support (yet) for such constructs, so doing 
this with the API directly is necessary.  There has been a contribution 
of a new parser that can work with SpanQuery which probably should be 
put in the sandbox soon.
