Phrase searching is one of the most powerful ways to search.
Use quotes to enclose key phrases. This will search for the words in the exact order that they appear.
"north by northwest"
When you search using SingleSearch you can replace characters in your search with one of two wildcards. You can replace any ONE character by using a question mark (?) For example, you can search for both the words Olsen and Olson by searching Ols?n.
The asterisk (*) will match any number of characters at the end of a word or within a word. Searching immigr* will search for words including immigrant, immigrate, and immigration. If you search col*r, it will search for both color and colour.
Remember though that wildcards cannot be used as the first character of a search.
