Filters

 Filters allow limiting search results independently of the query and determine how a query is applied. Most search tools have filters. Some offer unique filters other tools don't have. Use these when possible. Check to see what is offered at different search tools. Here are some possible filter types:

• Anchor - Find pages containing the specified word/phrase in a link.
