More About Search

Here are some guidelines that search uses.

• Insignificant words (a, an, the, of) are ignored.
• Search is not case sensitive.
• You cannot enter quotation marks around words to find exact phrases and you cannot use wildcards.
• Search does not find operators and special characters, such as +, so instead use the Index.
• If you are searching for information about an option, try including the hyphen (-) before the option, for example, save -append.
• The full text search type does not search the Online Knowledge Base.
• You cannot search for words in demos.
• If you search for a function but there are no results, try help function at the Command Window prompt. There are a few functions for which there is only M-file help.
• If you search for a function name that is used in multiple products (called an overloaded function), all the reference pages are listed. Use the Product column to identify the reference page for the product of interest.

Boolean Operators in Search.   The search automatically performs a Boolean AND for multiple words. In the example font preferences, it finds all pages that have both the word font and the word preferences, although the page might not necessarily have the exact phrase "font preferences".

You can refine the search by including the Boolean operators AND, OR, and NOT between words. The operators must be in all capital letters and there must be a space before and after each operator. The Boolean operators are evaluated in left to right order.

Example Using Boolean Operators in Search.   Type

• print OR printing AND figure NOT exporting
  

to find all pages that contain the words print and figure, or printing and figure, but only if the page does not contain the word exporting. At the top of the results list are any pages that contain all the ANDed and ORed words in the page title.
