- new : if the thesaurus has been modified since it's last indexation, it will be re-indexed as soon a record is to be indexed.
- nb : after thesaurus modification, the databox MUST be manually re-indexed (which will reindex the thesaurus before)
- todo : remove useless dialog boxes from thesaurus app (... "this term was..." "...add with/out reindexing ?..."). To be done in the future app using future routes.
