Keywords
Be specific. For example, if you're looking for information on Richard Nixon, enter "Richard Nixon" rather than "president."
The Gallup Brain search engine excludes common words and characters such as "of" and "the."
Capitalization
Searches are not case sensitive. All letters, regardless of how you type them, will be read as lowercase. For example, searches for "teen-age smoking," "Teen-age Smoking," and "Teen-Age SMokinG" will all return the same results.
Word Variations
To provide the most accurate results, the Gallup Brain automatically searches for derivatives of your keyword(s). For example, if you type the keyword "America," it will also find "American." Similarly, if you type "politic," it will also find "political."
