Most search engines give you the option of performing an advanced or complex or power search, in which you can narrow down the focus of your query. Complex searches use operators - words or symbols that instruct the search engine how to search.
Every search engine has a different way of constructing complex queries .
Complex search engine forms are made up of entry forms that allow you to set a few more parameters than what is available with a simple or standard search. As you will see, it's made up of pull-down menus, text entry fields, a checkbox and a search button. All complex search forms will have a text box for entering your query, some will rely more on your use of operators to set up the restrictions for the search, while others will provide you with pull-down menus, like the following one.
