For 44 million rows, FT will be much faster than LIKE. And do it with
where match(`value`) against ('+Hitachi +Brush +Cutter' IN BOOLEAN MODE)
Suggest you remove any "words" shorter than 3 letters and any "stop" words.
If you need to check for "Hitachi Brush Cutter" but not "Hitachi Cutter Brush", then I suggest
where match(`value`) against ('+Hitachi +Brush +Cutter' IN BOOLEAN MODE)
AND value LIKE '%Hitachi Brush Cutter%'
This is because the FT search will be fast and result in a small number of rows, which will then tediously be searched by LIKE. Net result: still very fast.
