Advanced Web Search helps you find sites that match very specific criteria. The search options you choose apply only to the current search. Please refer to the Search Preferences help page to learn more about your settings options.
To use advanced search options, click the Advanced link to the right of the Search box. Choose as many of the Advanced Search options as you like. Keep in mind that the more restrictions you set on your search, the fewer results are returned.

For more accurate results, there are some text boxes which give Yahoo! Search specific instructions about the words you enter. Many of these Advanced Search options can also be activated by typing Yahoo! Shortcut symbols into the basic search box.
* all of these words: Includes all of the words you typed in the search box. This is similar to inserting AND between words or the symbol + before a word.
* at least one of these words: Searches for results that match either one or more of the words. This is similar to inserting OR between the words.
* the exact phrase: Searches for the words in exactly the order you enter them. This is similar to putting quotes (" ") around a set of words.
* none of these words: Excludes words from your search. This is similar to inserting NOT between the words or the symbol - before a word.
