Mamma makes it easy for you to find what you need.  Most common operators are interpreted by Mamma, which properly formats queries and sends them to the best search engines on the Web.  However, we suggest using "+" and "-" for full effectiveness.  Also note that Mamma is not case-sensitive.

It's this simple: Go to any Mamma search box and choose where you'd like to look using the small radio buttons. There you can search the Web (the default), Usenet or newswires. Additional features are being added. Next, type the words or phrases that best represent the information you're looking for (in which case you should chose the search as phrase option). Now click the "Search" button.  

Here are some suggestions for fine-tuning your search.  

• Choose your words carefully.
• Be specific.
• When searching, consider words you might use to describe a subject if you were a webmaster. 
• When looking for a phrase choose the "Phrase Search" option. 
• You'll often be searching for a word pattern that appears just as you've typed it. Choose the "Phrase Search" option in order to force that exact sequence. This is very good way to look for a particular name.
• When you want to exclude words from the query use the minus (-) command in front of any word or phrase to screen out that term. 
• Use the plus (+) command to identify "must have" words or phrases.  Mamma will add a plus by default, so again, pick your words carefully.
• Another way of targeting a specific page is by conducting a document title search. All of the aforementioned operators apply when you select "document title" with the added capability of searching for a page title.
