This is happening because MySQL can't use two indexes, and neither
index can satisfy all the criteria. In some cases MySQL can use more
than one index for a query, but not when one of them is fulltext and
one is a B-Tree index.
You should be able to get the results you want with UNION. Write one
query that gets what you want from the full-text index, then another
that gets the things that can be found without it, then UNION them
together.
