filterRows not case sensitive?

[bw1kaeg0]

I try to implement a search function for a table. I use filterRows for filtering the table on the fly with each entered letter. Is there any way to make this filter non-case sensitive? Right now *XXX* displays other results then *xxx*

Could try to use this '*[Xx][Xx][Xx]*' as filter.
