search within sentence or paragraph

[Frederico Azeiteiro <Fr...@cision.com>]

Hi all,

 

Is it possible search for a combination of words within the same
sentence or paragraph?

 

Ex: American and McDonalds 

 

Returns : "McDonalds is a American company...."

Don't returns: "...went to McDonalds. After that se saw the American
flag..."

 

Is this possible?

Another perhaps more tractable approach is to have a token filter that  
bumps the position increment gap high when a sentence boundary is  
detected.  Then plain phrase queries will only match within a sentence  
(unless the slop factor extends beyond the gap distance).

Mark Miller's Qsol Parser can do that [1]. However it seems that temporarily it is not publicly available [2] [3].

The basic idea is to insert artificial tokens between sentences and paragraphs at index time analysis. And use SpanNotQuery at search time.
