Result of associated keywords too small

[mdemarne]

There must be a problem in the way OR requests are generated. The amount of tweets retrieve is highly likely to be too small compared to reality. For instance, the day of the match between Uruguay and Italy, the association of (Uruguay, Uruguai), (Italy, Italia), i.e. the request (Uruguay AND Italy) OR (Uruguay AND Italia) OR (Uruguai AND Italia) OR (Uruguai AND Italy) returned 7 tweets only, even if the number of tweets retrieved for both is very high.

BTW, a enhanced solution would also be to filter newly arrived tweets on one keywords internally to find if the second keyword occurs, and therefore base the association not only on Twitter's response to the combined query.
