Is it possible to bypass the minimum number of letters in a site search?

Question

vBulletin

It so happened that the word I needed is hidden in the bowels of the forum and it consists of only 3 words. But it turns out that in these engines themselves, by default, the minimum number of letters in the search is 4.
Is it possible to bypass this function somehow, because looking for a word of 3 letters yourself is murder.
And yes, vBulletin is worth it.

Answer 1

Answer 2

The word is probably beaten off with spaces on both sides, isn't it?
