keywords: manage the thesaurus

Hi,

with an Admin profile, it could be useful to cleanup the thesaurus of keywords in order to limit too many wrong answers with the searches.

for example: some keywords can be misspelled (two spellings for one asset), or delete some keywords from the thesaurus, etc.

So it could be useful to export or manage this thesaurus, cleanup it and reimport it.

Maybe with a comparison system as we can find for files comparisons.

Thank you
