Disable auto-complete (Google) Check (select) this option to prevent Google instant search from auto-suggesting search queries.
Select blocked search keywords to filter Once you create Blocked Search Keyword lists you can enable them on your Rule Sets.

Note: 
The Web Filter fully supports Google and Bing search and image controls. Search queries and images on other search engines may not be fully blocked due to the restrictions of the search engines themselves.

Tip: When Unknown URLs, Domains and IP Addresses are blocked, the web filter is unable to display thumbnails for image searches using the Research tool in Google Documents and Presentations. This is because the Research Tool does not append a source URL or domain to the search string, which the web filter requires for filtering.
