Boolean Searching

In order to get the most relevant hits at the top of the list, various techniques are applied that may be very different from one another. Each search robot has its own system of:

collecting sites and adding to the database;
organizing sites in the database;
searching the database;
establishing relevance
presenting information

A small difference in one of these four elements will affect the results of the search action. This is one of the reasons why results differ for each robot when you are using the same terms as search options. This is also why you should always consult more than one search robot.
