SpanOrQuery with unreasonable high scores

2010-12-07 Thread Jan Kurella 

Hi,

From what I got, the SpanOrQuery is similar to a BooleanQuery with 
Or-Clauses. It can be used in other span queries.
But compared to the BooleanQuery it has a significant difference: It is 
missing a querynormalization. Thus by the just summed up idf of all 
tokens in the query, even documents with just one hit get an extremely 
high score as mainly the idf is relevant for scoring.


To have some query normalization like in BQ one qould need to cascade 
the SpanWeight.normalize(float) down to the Spans (and its containing 
subSpans). But unfortunately neither is the Spans existing at this point 
in time nor does the Spans concept support boosts or norms.


so how do I get the SpanOrQuery best normed to be comparable to a 
BooleanQuery?

I haven't a clue about the package protected thing, but
you may not need to go there. This sounds a lot like
DisjunctionMaxQuery, have you looked at it?

RE: Help Overriding behavior in BooleanQuery scorer

2010-12-07 Thread Ryan Aylward 
Thanks very much for the response, Erick.

I think one of my co-workers tried to use it and seemed to think it
didn't meet our needs but I'll give it a shot.

In the meantime, I'm curious to see if anyone else has modified
BooleanQuery to modify how calculates the score. Is the only way to do
that to make a copy of the classes?

java.lang.NoClassDefFoundError:org/apache/lucene/search/similar/MoreLikeThis

2010-12-07 Thread starz10de 



Hi All,

I am using MoreLikeThis class in lucene to find more similar documents in
the index to the giving one. It works fine when I run it directly from
Eclipse but when I call it from my servlet I have this error:

“java.lang.NoClassDefFoundError:org/apache/lucene/search/similar/MoreLikeThis“

Any idea why this error occurred?

Thanks

It sounds like the jar containing the MoreLikeThis class in a place that
your servlet
can find it. It's in contrib, something like lucene-queries.jar

You can use DBSight for database search. You just need to give it one or 
several SQLs. And you can generate search result template, and it will manage 
the index for you.
