Full-text search: Problems with dictionaries and periods

[Theron Luhn <theron@xxxxxxxx>]

I made a custom synonym dictionary for my full-text search, using the following code from the documentation.

CREATE TEXT SEARCH DICTIONARY my_synonym (
    TEMPLATE = synonym,
    SYNONYMS = my_synonyms
);

ALTER TEXT SEARCH CONFIGURATION english
    ALTER MAPPING FOR asciiword WITH my_synonym, english_stem;

It works great, except on words with periods in them.  For example, B.B.Q.:

=> select * from ts_debug('english', 'B.B.Q.');

 alias |    description    | token | dictionaries | dictionary | lexemes 

-------+-------------------+-------+--------------+------------+---------

 file  | File or path name | B.B.Q | {simple}     | simple     | {b.b.q}

 blank | Space symbols     | .     | {}           |            | 

(2 rows)

It interprets the string as a filename (that's what alias: file means, right?), so the asciiword dictionary I set up above doesn't apply.

How can I change this?
