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.
