Keyword Filter
The Keyword Filter blocks web pages based on the words they contain. Add the words you want to restrict to a Keyword Filter, and students cannot reach pages that include them. Because the filter matches words rather than specific web addresses, it restricts inappropriate or irrelevant content wherever those words appear.
Note
Keywords match whole words only. For example, the keyword rap blocks pages containing the word rap, but not pages containing photography.
Each Keyword Filter has its own behavior setting that controls what content is scanned. Choose one of the following options when configuring a Keyword Filter:
Scan whole page content on all pages - The page is blocked if a keyword appears anywhere in its content, including search queries and search result snippets. This is the default option.
Match search queries only - The search results page is blocked only if a keyword appears in the search query. Other pages and search results are not scanned, which reduces false positives.
Important
A Custom Category or an Exception List can override the Keyword Filter. If a keyword blocks a website, you can allow that website by adding it to a Custom Category or an Exception List as an allowed entry.
To access the Keyword Filter page, click Content Filtering from the Main Menu, then click Filters from its sub-menu. On the Filters page, click Keyword Filter listed under Context Filters.
Important
After making any changes to your content filtering or policies, click the 
button in the Action Bar at the top of the page to apply the changes.
Identifying the Keyword That Caused a Block
When a keyword blocks a page, the Access Denied page shows the keyword's position number and the ID of the Keyword Filter it belongs to. For example, #3 is the keyword's position and 40b391df is the filter ID.
On the Keyword Filter page, locate the filter with the matching ID in the Filter ID column and click its 
button. In the keyword list, find the keyword with the matching position number, shown to the left of each keyword.
To set up a Keyword Filter, create the filter, set its behavior, then add the keywords you want to block.
Type a name for the filter in the Enter filter name text box, then click the
button. The new filter appears on the Keyword Filter page.
Click the
button in the same row as the new filter. The Edit Keyword Filter page opens.
In the Keyword filter behavior section, select one of the following options:
Scan whole page content on all pages - The page is blocked if a keyword appears anywhere in its content, including search queries and search result snippets. This is the default option.
Match search queries only - The search results page is blocked only if a keyword appears in the search query. Other pages and search results are not scanned, which reduces false positives.
