--- Comment #1 from Kevin Suo <suokunlong at 126.com> ---
Copying Caolan's comment:

"It looks to me that it loops over every cell in the column and compares each
cell to every selected option in the ui list by looping over every one of
those. My guess is that for this specific case where we want to see if each
cell has a match in the list that we should do something like special case the
search by lowercasing all the entries in the list and putting into a
sorted_vector so we can look up directly if the lowercase text in each cell has
a matching entry in that list".
