minimum range for SpanQueries

2009-12-21 Thread Christopher Tignor
Is there are way to implement a minimum range for a SpanQuery or combination thereof? For example, using: "The boy said hello to the boy" I'd like to use a SpanNearQuery consisting of the terms "The" and "boy" that returns one span including the entire sentence but not a span for the first two w

I don't think that will work, as I don't believe that the SpanQueries delegate scoring to the subclauses. Instead, they just rely on iterating the spans. -Grant On Dec 21, 2009, at 2:44 PM, Uwe Schindler wrote: > It is as you describe: > > PayloadTermQuery is a subclass of SpanQuery. So creat

How can I add the first the PayloadNearQuery, I only add clauses.. (It is only one term I did the following code - this code doesn't provide the needed effect). SpanTermQuery [] spanTerms = new SpanTermQuery[terms.length]; spanTerms[0] = new PayloadTermQuery(new Term(field,terms[0]),new AveragePa

It is as you describe: PayloadTermQuery is a subclass of SpanQuery. So create a SpanNearQuery with slop=0 and order=true and add first the PayloadNearQuery, then the rest of the phrase terms as SpanTermQuery in order of appearance. Uwe - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen htt

2009-12-21 Thread Ian Lea
Hi The standard approach to paging is just to do the search again and pick out the docs you want, along the lines you outline. You cannot pass start/end info to any search methods. When you set max doc to, say, 10, lucene will find the 10 highest scoring docs and return them. There is no point

that's a good idea. This approad will work. Supposing someone submit a query "nice rice restaurant", I think he/she wants to find a chinese restaurant. But you will find the category of "restaurant" retrieved with higher score than "chinese restaurant". Usually you may find no category retrieved b
