> PR contains improvements when Anys are searched using FIQL queries:
> The resulted SQL query that finds any_to_keys can have a huge list with OR clauses for
effective realms. This can be replaced to the IN clause.
> {code:sql}
> SELECT u.any_id,sv.username FROM (SELECT DISTINCT any_id FROM user_search WHERE (realm_id=?
AND any_id IN ( SELECT DISTINCT any_id FROM user_search WHERE lastChangeDate<=?))) u,user_search
sv WHERE u.any_id=sv.any_id AND u.any_id IN (SELECT any_id FROM user_search WHERE realm_id
IN (SELECT id AS realm_id FROM Realm WHERE id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR
id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=?
OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=?))
ORDER BY sv.username ASC
> {code}
> When anys are searched by keys a lot of single sql queries are executed. This can be
improved using single SQL query with In clause.
