result limit / diversity with an OR query

[s d <s....@gmail.com>]

Hi,I have a query similar to: x OR y OR z and i want to know if there is a
way to make sure i get 1 result with x, 1 result with y and one with z ?
Alternatively, is it possible to achieve through facets?
Thanks,
S.

the easy answer is: x AND y AND z . This will return ALL the documents 
containing x,y and z. But if you want also get the documents containin 
AT LEAST one of the three, try this:

(x AND y AND z)^100000 OR (x OR y OR z)

(the idea is boosting the AND query)

this way, the documents that "x and y and z" exists, they will be the firsts

The easiest way is to execute three separate queries:
+x y z
x +y z
x y +z
