Some of search engines have two versions - filtered and un-filtered for search page . To find out what the difference is, just try unfiltered for a short while in the following search engines:
Alltheweb / AOL Hot Searches /
InfoTiger / SeekDrive Live
A perpetually refreshing page that provides a real-time view of actual web search results.While not as immediately useful as keyword databases that summarize monthly totals, search engine spies can give insight into how people actually search. (Some keyword databases, such as the Goto.com tool, alter the raw searches to assist grouping.)
Search engine spies come in filtered and unfiltered varieties. Filtered services are in an attempt to remove "objectionable" search results. Some spy services only offer one or the other, some offer both options and let you choose.
