Spell-check search queries, à la google. E.g. searching on [vacum cleener] should ask if you meant/search on [vacuum cleaner].
Search also for synonyms. E.g. [secateurs] gave me no results, but [pruner] did. It would be good if the latter search was automatically done given the former query.
Have someone proofread.
For searches on misspelled words
"Type Less Words" s/Less/Fewer/, though your search doesn't match fewer results when more search words are added.
"Type Words Correct Spelling", perhaps just "Correct Spelling". But, if a word does not match anything, run it through aspell with an aspell dictionary created from your product lists.
