Select with string that has a lone hyphen yields nothing - Mailing list pgsql-general

I have a product names table like this:

datab=# select product_id, name from table.product_synonyms where name
ilike '%%olympus e-pl1%%';
 product_id
|
name
------------

+---------------------------------------------------------------------------------------------------------------------------------------
       8736 | Olympus E-PL1
       8736 | Olympus E-PL1 Interchangeable Lens Type Live View
Digital Camera – Black (Body Only) (Call for pre-order. Available on:
2010-04-09)
       8736 | Olympus E-PL1 Interchangeable Lens Type Live View
Digital Camera – Blue (Body Only)
       8736 | Olympus E-PL1 Interchangeable Lens Type Live View
Digital Camera w/ ED 14-42mm f3.5-5.6 (champagne/gold)
(4 rows)

Any select statement prior to the hyphen yields a result, but from the
hyphen on yields nothing:

datab=# select product_id, name from table.product_synonyms where name
ilike '%%Olympus E-PL1 Interchangeable Lens Type Live View Digital
Camera -  Blue %%';
 product_id | name
------------+------
(0 rows)

Any ideas how to fix this?
