Re: Making SpanQuery more effiicent

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 On 5/25/06, Michael Chan <[EMAIL

I see. Also, as I'm only interested in the number of results returned and not in the ranking of documents returned, is there any component I can simplify in order to improve search performance? Perhaps, Scorer or Similarity? Thanks. Michael On 5/24/06, Chris Hostetter <[EMAIL PROTECTED]> wrote

Hi, As I use SpanQuery purely for the use of slop, I was wondering how to make SpanQuery more efficient,. Since I don't need any span information, is there a way to disable the computation for span and other unneeded overhead? Thanks. Michael ---
