Hi Abraham,

Yes, but you need to supply Custom Generator and Filter functions.
The documentation has an example for this in "Multiple Indexes", where a
telephone number being searched for may be in the landline *OR* in the mobile
index. The example uses the existing 'relQs' function which in turn generates
the necessary generator and filter functions.

Perhaps, but it is a bit tedious to supply the proper functions.
What are the "tags" in your case? As you talk about "link"s, I assume they are
(+Ref +Link)s to other objects.
If so, if we take itams and supuliers from the demo app, then items can be
searched by suppliers. Let's assume we have a list of 2 suppliers ({C1} {C2}),
we can search for their items with:
(for
(Q
(search
'({C1} {C2}) # List of suppliers
(quote
((X) (cons (list X) pop)) # Generator
((X Val) (memq X Val)) # Filter
(sup +Item) ) ) # Association to item by 'sup' index
(search Q) )
(show @) )
