Recommendations search, apostrophes

A search problem with recommendations that I have noticed for a long time: Searching a title with a word that includes apostrophes either takes a long time (or it works but this is rare) or doesn't bring up anything (usually I get tired of waiting and remove the apostrophied word and try again). A search with the apostrophied word works fine and quickly on the "ordinary" LT search at top right.

An example when making a recommendation where the apostrophe is a problem:
thing's concert

That title actually did not turn up, but two unrelated books did.
(Yes the book is on LT
http://www.librarything.com/series/Thing+-+Klein )

Searching: concert klein
in recommendations did bring the book up.
Searching: thing's concert klein
in recommendations brought up nothing.

Trying all three on LT's search box at top right to compare:
thing's concert klein - result came up, yes
concert klein - result came up, yes
thing's concert - result came up, yes
No problems there. The problem is with recommendation's search.

Here is an example with an apostrophe that works, no problems:
LT search: In summertime it's Tuffy Judie Angell - result came up, yes
Recommendations search: In summertime it's Tuffy Judie Angell - result came up, yes
So it seems to vary whether the result comes up or not. This one was fine. Does it depend on where the apostrophe is? Or is there some other variable?

I bet "it's" is a stopword - that is, search identifies and ignores it (as it does the, an, a...). Otherwise it has to check way too many words. But the other is actually searched on and fails.

I'm not actually sure what you mean by "recommendations search"; do you mean the lightbox that crops up when you begin to make a recommendation?

Add your own recommendation> FIND BOOK
That's the search box.

So, that's a yes then.
