The AltaVista help pages enable you to get the most from your search experience.  AltaVista Search is one of the most powerful tools on the Internet, and we are dedicated to helping you use its features to their maximum potential.
The main difference between the two is the ability of Advanced Search to use Boolean expressions. Boolean expressions are the words OR, AND, AND NOT, and NEAR used to create relationships among the keywords in your search query. Using these expressions allows you to tailor your search to find exactly what you are looking for.
Advanced Search also allows you to sort your results, specify particular dates in your query and more. These functions, along with Boolean expressions, are explained in greater detail below.
1.Type (ballroom OR salsa) AND dance in the Boolean query box. This Boolean query will find all documents containing the phrases 'ballroom dance' and 'salsa dance.'
2.Type tango waltz in the 'Sort by:' box. This step sorts the documents so that tango and waltz appear at the top of your results.
3.Type 01/JAN/99 in the From: box and 30/JUN/99 in the To: box. This step limits the results to documents that have been updated in the first half of 1999.
Note: If you do not include a month or year in the From: or To: fields, the search will use the current month and year.
