[FIX] web: reset offset in the search more view dialog

Start on the modal obtained by a "search more". The offset is never reset.
So suppose you are on page 2, looking at record 81-160.
Do a research that gives less than 80 records.
The result of the search is nothing, since is has been done with a 80 offset.
It should be reset to 0 when we do a new search.
