Can vbulletin internal search find these keywords?
 

Say I wanted to search for the following strings (which currently return empty results in fulltext when a minimum word length of 3 is set):

'fa* 24'
'kx'
'k-7'
'85mm'
'k7 lens'

Would the vbulletin built-in search be able to find them?
Also, is it even feasible to switch from fulltext on a board of my size?
