Subject Re: Making SpanQuery more effiicent
Date Thu, 25 May 2006 13:32:07 GMT
After some more research, it seems that one of the bottlenecks is
Spans.next(), can I drop anything out in order to improve performance?
Most of the queries are SpanNearQuery with SpanOrQuery as its clauses.

Any help would be much appreciated.

Regards,

Michael
