Some search engines allow you to type in questions as you would think or speak them. You often will want words to appear together in specific order. In large documents, words separated by lots of text are generally unrelated. ADJ specifies that two words appear next to each other. It allows you to specify that the search words appear in the title, URL, or first paragraph.
Most search engines are case insensitive by default.
However, there are some that recognize uppercase and lowercase variations. Copyright 1998 American Library Association. Used by permission of ALA Editions. Reproduction for nonprofit educational purposes permitted. Copyright 1998 American Library Association.
