Narrowing Searches

Specifically applies to AltaVista, but the idea is fairly general.

1. What is a word? A phrase?

2. By default, words and phrases are ORed.

3. Use of lowercase and uppercase: case sensitivity.
   1. paris: paris, Paris, PARIS.

   2. Paris: Paris.

4. Using + to include and - to exclude. Using + for AND.
   1. recipe cookie +oatmeal -raisin

5. Wildcards:
   1. gold*: gold, golden, goldsmith, goldilocks, Goldilocks, etc.

6. Restrictions on where to look:
   1. title:

   2. domain:

   3. host:

Example: Using AltaVista, look for information on Parris Glendenning's environmental record. Start with ``parris.''
