Bug #47930: MATCH IN BOOLEAN MODE returns too many results
inside subquery
Re-setting a fulltext index was a no-operation if not all
the matches of a search were consumed by reading them.
This was preventing a joined table using a fulltext index
in a subquery that requires only 1 row of output (e.g. EXISTS)
from working correctly because the second execution of the
sub-query has the fulltext index cursor in a wrong state and
was not finding results.
Fixed by making the re-init code _ftb_init_index_search()
to re-set open cursors in addition to depleted ones.
