by definition :)
read http://www.sai.msu.su/~megera/oddmuse/index.cgi/tsearch-v2-intro

Lets attempt to use the function with a string of multiple words:

         SELECT to_tsquery('default', 'this is many words');

         ERROR:  Syntax error

The function can not accept a space separated string. The intention of the
to_tsquery function is to return a type of "tsquery" used for searching a tsvector field. What we need to do is search
forone to many words with some kind of logic (for now simple boolean).
