What Are "Meta-Search" Engines? How Do They Work?

Are "Smarter" Meta-Searchers Still Smarter?

"Smarter" meta-searcher technology includes clustering and linguistic analysis that attempts to show you themes within results, and some fancy textual analysis and display that can help you dig deeply into a set of results. However, neither of these technologies is any better than the quality of the search engine databases they obtain results from. This is the topic of an insightful article titled, "Some Cautionary Notes on Vivisimo," by librarian and professional researcher, Rita Vine of Working Faster. But here is another viewpoint favoring meta-searching by saying "More heads better than one."

Few meta-searchers allow you to delve into the largest, most useful search engine databases. They tend to return results from smaller and/or free search engines and miscellaneous free directories, often small and highly commercial.

Although we respect the potential of textual analysis and clustering technologies, we recommend directly searching individual search engines to get the most precise results, and using meta-searchers if you want to explore more broadly.

The meta-search tools listed here are "use at your own risk." We are not endorsing or recommending them.

Better Meta-Searchers

Meta-Search Engines for SERIOUS Deep Digging

Meta-Search Tool	What's Searched (As of date at bottom of page. They change often.)	Complex Search Ability	Results Display
SurfWax www.surfwax.com	A better than average set of search engines. Can mix with educational, US Govt tools, and news sources, or many other categories.	Accepts " ", +/-. Default is AND between words. I recommend fairly simple searches, allowing SurfWax's SiteSnaps and other features to help you dig deeply into results.	Click on source link to view complete search results there. Click on to view helpful "SiteSnap™" extracted from most sites in frame on right. Many additional features for probing within a site.
Copernic Agent www.copernic.com	Select from list of search engines by clicking the Properties button following Advanced Search search box.	ALL, ANY, Phrase, and more. Also Boolean searching within results under Refine (powerful!).	Must be downloaded and installed, but Basic version is free of charge. Table comparing versions.

CSEs: Make Your Own Meta-Search Engine

Google Custom Search Engines (CSEs) focus on selected websites within the Google database. They are easy to make at Google Coop. You will need a Google account or Gmail account. Make specialized search engines instead of using giant meta-searchers or huge search engine databases. Use them to focus on pages on a subject. For more details, see our Getting Started Creating a Custom Search Engine (PDF).

How Do You Find Custom Search Engines

Search Google using the following limiter commands, followed by keywords focusing on your topic:

inurl:cse inurl:coop site:google.com   anthropology
inurl:cse inurl:coop site:google.com   physics

Try searchnig or browsing in one of these CSE Directories:

• Guide To Custom Search Engines (CSEs)

  www.customsearchguide.com

  Large number of CSEs, good content. Reviews & ratings. No search box. Navigation inconsistent: some have search boxes, some require click on "CSE location."

• The Directory of Google Custom Search Engines

  www.customsearchengine.com

  Large number and variety of CSEs. Easy to use. Searchable. Lacks reviews; few ratings. Most have brief descriptions.

• CSE Links Directory - Custom Search Engines

  www.cselinks.com

  Sparsely populated directory. Has search (top), ratings, comments, pop-up previews.
