open the attached sample vector and try to search in the table of attributes with the new column filter (column @descri@) for the phrase

@Montados de azinho com pastagem no subcoberto (<50%)@

it won't work. But If you search just

@Montados de azinho com pastagem no subcoberto@

or

@(<50%)@

will work.

It's mostly fixed.
It was caused by a bug in QgsExpression, parsing a LIKE clause like a regexp.

It's still not possible to escape % and _ signs with the LIKE operator but now it the misbehavior is to match more rows instead of less rows. Followup opened here:
