Multiple Tokens

Here is an example of how tokens are assigned values. Suppose that you are going to

search the following text:

andy ted bob jim andrew andy ted mark

You choose to search the above text with the following search pattern:

and(y|rew)|(t)e(d)

This pattern has three parenthetical expressions that generate tokens. When you finally

perform the search, the following tokens are generated for each match.

Match Token 1 Token 2

andy y

ted t d

andrew rew

andy y

ted t d

Only the highest level parentheses are used. For example, if the search pattern and(y|

rew) finds the text andrew, token 1 is assigned the value rew. However, if the search

pattern (and(y|rew)) is used, token 1 is assigned the value andrew.
