Formatting your queries makes it much easier for people reading it to
try and help you.
This query looks like an unconstrained join. Judging by the query
plan that explain returns, I'd sau that is the case.
What, exactly, are you trying to do here? I'd think that a union of
two queries with those where exists clauses as where clauses and a
proper join on the semtable might work beyyer.
