Maybe these are trivial questions but I could not find a solution on the forums.

Can I do search libraries and sub-libraries titles? I have about 100 sub-libraries and it is quite time consuming to search.

And, after doing a search on items, is there a way to identify the sub-library of a specific item.

I know, it's not a big deal, I can do without it, but when the data set is large, it can be very helpful.
thanks, Arie
