NOTES: Search engine keyword filtering relies on an exact
keyword match. For example, if the word "sex" is set up to be
blocked, but "sexes" is not set up to be blocked, a search will be
allowed on "sexes" but not "sex". However, if the word "gin" is set
up to be blocked, a search on "cotton gin" will be blocked since
the word "gin" is blocked.
To set up search engine keywords in a Search Engine Keywords
window for Custom Categories, see Chapter 2: Library screen,
Search Engine Keywords window.
URL Keyword Filter Control
With the URL Keyword Filter Control option enabled, URL
keywords can be set up to be blocked. When a user enters
a keyword in the address line of a browser window, if that
keyword has been set up to be blocked, the user will be
denied access to that site or service. URL keywords are
entered in the URL Keywords window of custom library
categories.
With the "Extend URL Keyword Filter Control" option
enabled, a URL keyword search will be extended after the
"?" character in a URL.
NOTE: To set up URL keywords in a URL Keywords window for
Custom Categories, see Chapter 2: Library screen, URL
Keywords window.
WARNING: If this feature is activated, use extreme caution when
setting up URL keywords for filtering. If a keyword that is entered
in a browser's address window contains the same consecutive
characters as a keyword set up to be blocked, users will be
denied access to URLs that are not even within blocked catego-
ries. For example, if all URL keywords containing "sex" are
blocked, users will not be able to access a non-pornographic site
such as http://www.essex.com.
