Search hints:

Fill in as much as you'd like. Using more than one line will narrow the search. If you choose Yes for "Words adjacent" you can type in the phrase computer programming and the system will understand that you want only records that have the word computer NEXT to the word programming.

Lower-case letters will find matches of capitalized words also. For example, computer will find matches for computer, Computer and COMPUTER.

You may use the Boolean operators AND and OR in your search string. For example, you could type (heart OR cardiac) AND surgery to retrieve all records having heart or cardiac in them, together with the word surgery.

Use the ? character to find matches that contain portions of words. For example, gun? will retrieve gun, guns, gunners, gunnery, gunning, etc. In another example, ?ology will retrieve anthropology, archaeology, psychology, etc. The ? character may also be used to find variant spellings. For example, alumi?m will find both the American spelling, aluminum, and the British spelling, aluminium.
