Currently it seems like that dot is not considered as a word delimiter
by the english parser.
lawdb=# select to_tsvector('english', 'Mr.J.Sai Deepak'); to_tsvector
-------------------------'deepak':2 'mr.j.sai':1
(1 row)
So the word obtained is "mr.j.sai" rather than three words "mr", "j",
"sai"
It does it correctly if there is space in between, as space is
definitely a word delimiter.
lawdb=# select to_tsvector('english', 'Mr. J. Sai Deepak'); to_tsvector
---------------------------------'j':2 'mr':1 'sai':3 'deepak':4
(1 row)
I think that dot should be considered by as a word delimiter because
when dot is not followed by a space, most of the time it is an error in
typing. Beside they are not many valid english words that have dot in
between.
