OPE and FILE SEARCH / criteria are not cumulatives and search bugs
in OPE and FILES search (modif) the criteria don't seems to be cumulative (diag + villa for example).
May be a more global session bug as :
a search that should produce no result keept the old result in the table result,
even with a change in the default menu the same old result are given.
At this time the search process doesn't work, as a blank result is a result that is not displayed.
