You can use 'and', 'or' and 'not' between your keywords; 'and' applies by default.

The following examples illustrate the kind of expressions that you can use to search the index(es):

• construction industry
• materials science or materials processing
• biology and (cell or protoplasm)
• precollege not (middle and school)
• test* (finds test, tests, testbed, etc.)

Note

1. The search evaluates an expression from left to right.
2. The expressions in parentheses will be evaluated first.
3. Wildcards (asterisks) can be used only at the end of a single word.
4. To search for words containing 8 bit characters, use the nearest 7 bit equivalent. For example, to find resumé, search for resume.
