Searchlogic to check whether two arrays intersect

How can I use searchlogic to check whether two arrays intersect? I
have User.array_1[] and the search criteria are in Search.array_2[].
I want to search for all users whose has an array_1[] that intersects
with Search.array_2[] . That is where (user.array_1 &
search.array_2) != nil . How can I do this with searchlogic?
Thanks.
