Good tip, thanks MartynMartyn said:It can be lowered, but the impact on the server is huge.
Just use a wilcard - and asterisk - beore or/and after the word:
axe*
*GB*
fak*
etc....
the asterisk counts as a character for the search, but it will also yield other words, so a search for axe* will give you "axe" and "axed" etc.
