Searching Strategies

Does your web tool permit you to use a pearl growing or successive fractions technique?

In both of these techniques you can predict the number of records that will result from a boolean operation.

Pearl growing uses the OR operator to add more records to a nucleus of records at hand Can you OR new terms to an established query? Is the size of the resulting set predictable? For example:

(1st search) dog

(2nd search) The results of the 1st search OR cat

(3rd search) The results of the 2nd search OR bird

etc.

Successive fractions can be done with either the AND or the NOT operator. Using either of these operators should reduce the size of your search sets. Can you AND new terms to an established query? Is the size of the resulting set predictable? For example:

(1st search) dinner

(2nd search) The results of the 1st search AND lunch

(3rd search) The results of the 2nd search AND breakfast

etc.

Is your web tool sensitive to precedence errors?

What do you get if you enter

(dog and cat) adjacency food

(* Note: use the appropriate adjacency operator for your web tool.)
