I noticed in elastic search (ES), you can do queries like
a b~4
I think this query will match stuff like a b and a x x b but not
something like a x x x x x x x x b.
I'm not sure if this kind of thing is possible with postgresql full
text search. Is it possible?
I understand that I can do
something like this ?
