Search is not trimming

Hey!

Let's say one of the columns has the words Free Ads.
If I search for fre, it will filter the row(s)
if I search for ad, it will filter the row(s)
However, if the user types a space after or before the above searches, it won't bring any results.
The source code seems to have some searchText.trim() in it, but it does not seem to help in those cases.

How can I trim what the user is typing?

Thanks in advance,

Sergio
