Feel free to use wildcards ("*" and "?") in searches. The search engine searches product codes, descriptions and details and all other web content (news stories, etc.), so it helps to use search expressions that will return an accurate list of the results you want.
A wildcard is a character that may be used in a search term to represent one or more other characters. The two supported wildcards are:
? — The question mark ("?") may be used to represent a single alphanumeric character in a search expression. For example, searching for the term "ho?se" would yield results which contain such words as "house" and "horse".
* — An asterisk ("*") may be used to specify zero or more alphanumeric characters. For example, searching for the term "h*s" would yield results which contain such words as "his", "homes", "houses", "horses", "horticulturalists", and "herbaceous". It is usually best to avoid using the asterisk as the first character in a search string. A search term consisting of a lone asterisk and no other alphanumeric characters will retrieve everything.
