: But when I do a search for allergy , I get 0 results
You've configured your field so that any time the terms "allergy"
and "test" appear in sequence in a field value you index, those terms are
removed and replaced by new terms ("Doctors", "Doctors-Medical", etc...)
So if the term "allergy" only appears in the source text followed by the
term "test" then it will never actually be indexed in your document, so a
serach for it will never match.
You can see this exact behavior in the screen shot you posted of the
analysis tool...

...after the synonyn filter, the term "allergy" is not in your indexed
terms.
: when i change the synonym file to a comma separated I am able to see the
: results
because when using a comma instead of "=>" you are saying "if any of these
term sequences exist, expand it to *all* of these term sequences.
Please note the docs on SYnonymFilter, particularly the examples...
