Page 136 Communicating Using Your Handheld Computer
Defining filter strings
E-mail items are filtered based on the information contained in their
To:, From:, and Subj: fields. The information that defines what your
handheld computer is looking for is called a
filter string . You create a
filter string by listing the words you want your handheld computer to
find and separating them with either a comma or a space. Each word
in the filter string is joined by an implicit OR, so you do not need to
enter logical connectors like AND or OR.
To create a more complex filter, you can define filter strings for the To:,
From:, and Subj: fields simultaneously. Your handheld computer joins
the filter strings for these fields using an implicit AND; once again,
you do not need to add the logical connector. Your handheld
computer does that for you.
For example, suppose you want to receive only e-mail items from John
Smith (jsmith@aol.com) or Jack Jones (jjones@aol.com) concerning the
Apollo Project. You would create the following filter strings:
In the To: field:
jsmith@aol.com, jjones@aol.com
In the Subj: field:
Apollo Project
Your handheld computer interprets this as, “Accept e-mail items
about the Apollo Project from John Smith or Jack Jones. Do not accept
e-mail items from other people. Do not accept e-mail items from John
or Jack about any other subject.”
When you define a string, note that your handheld computer searches
for any instance of that
sequence of characters. For example, if you
create a filter that retrieves only e-mail items containing the string
“info,” your handheld computer considers “
info ,” “ra info rest” and
“k info lk” appropriate matches.
Retrieve
Only Msgs
Containing Tells your handheld computer to include
only the e-mail items that meet the criteria
you define and to ignore all other e-mail
items during synchronization. This filter
has the potential to block more e-mail
during synchronization because it
downloads only one subset of e-mail.
