[Xapian-discuss] Extract common phrases from index

[Josh]

Is it possible to extract common phrases from an index?

Basically, I'd like to index my document set and find words that
commonly appear next to each other.

For example if I a set of recent political news articles I may expect
to find "John McCain", "Sarah Palin" and "Barrack Obama".

Ideally I'd like to specify any number of words (all 2 word phrases,
all 3 word phrases).

Possible? Crazy? Point me the right direction.

Thanks!
Josh
