retrieving matched slop

[Ruslan Sivak <rs...@istandfor.com>]

I have an app that searches a single document against many queries.  
Lets say the document was

The quick brown fox jumped over the lazy dog.

and my queries are

SpanNearQuery("quick","brown",50)
SpanNearQuery("quick","fox",50)

I would like to retrieve the slop or some sort of score that was matched 
when I'm searching.  Since the first one requires no slop, it would 
return 0 or the highest score and the second query would return 1 for 
slop as fox is one word away from quick.  Is there any way to retrieve 
these values?

Re: retrieving matched slop

[Chris Hostetter <ho...@fucit.org>]

there's a few options...

you can define a custom SImilarity that makes the score based entirely on
the sloppyFreq ... it's not trivial, but it's certainly possible.

the other option is to call SpanQuery.getSpans directly, and then iterate
over it and compare end() - start() for each span.
