The Meta Search Engines: A Web Searcher's Best Friends
I know what you're thinking: Google gives you such accurate
results that you don't need any other search tool. Well, let's see about that.
You might - or might not - know that no major search engine indexes ALL the existing Web
pages. OpenFind states that it indexes 3.5 billion Web pages, Google claims 2.4 billion,
AllTheWeb - 2.1 billion, Inktomi - a little more than 2 billion, WiseNut - 1.5 billion and
AltaVista - 1 billion Web pages.
The truth is, nobody knows how wide the Web is. Some say 5 billion pages, some 8 billion,
some even more. Anyway, what's definite is that the major search engines (SEs) index only
a fraction of the "publicly indexable Web". Moreover, every SE indexes
different Web pages, which means if you use only one SE you will miss relevant results
that can be found in other search engines.
One way to more effectively search the Web is to use a meta search engine.
What is a Meta Search Engine?
A meta search engine (also known as a multi-threaded engine) is a search tool that sends
your query simultaneously to several search engines (SEs), Web directories (WDs) and
sometimes to the so-called Invisible (Deep) Web, a collection of online information not
indexed by traditional search engines. After collecting the results, the meta search
engine (MSE) will remove the duplicate links and, according to its algorithm, combine/rank
the results into a single merged list.
An important note:
Unlike the individual search engines and directories, the meta search engines:
1. Do not have their own databases and
2. Do not accept URL submissions.
Pros and Cons of Meta Search Engines
Pros: MSEs save searchers a considerable amount of time by sparing them the trouble
of running a query in each search engine. The results - most of the time - are extremely
Cons: Because some SEs or WDs do not support advanced searching techniques
such as quotation marks to enclose phrases or Boolean operators, no (or irrelevant)
results from those SEs will appear in the MSEs results list when those techniques are
MSEs Come In Four Flavors
1. "Real" MSEs which aggregate/rank the results in one page
2. "Pseudo" MSEs type I which exclusively group the results by search engine
3. "Pseudo" MSEs type II which open a separate browser window for each search
engine used and
4. Search Utilities, software search tools.
provides detailed information on each of the four MSE types, along with my ranking:
1. Real MSEs
These real MSEs simultaneously search the major search engines, aggregate the results,
eliminate the duplicates and return the most relevant matches, according to the engine's
algorithm. Following is a list of a few meta search engines that you might find
useful. It's by no means complete, but it might help you find what you need. (The
criteria I used to determine the best MSEs were: the amount and the relevance of the
results, the capability to handle advanced searches, the ability to enable users to
customize searches, and the speed of their searches.)
Ez2find - (formalerly ez2www) http://ez2find.com
Searches the best SEs - AllTheWeb, Google, AltaVista, Teoma, Wisenut - and directories - Yahoo! and Open Directory. Through its "Advanced Search" function it also searches a small part of the Invisible (Deep) Web. It also searches news, newsgroups, MP3, images and many, many more.
Provides excellent results in a very neat interface. Created in September 2000 by the French search engine developer Holomedia. THE best!
Vivísimo - http://vivisimo.com
Uses the clustering technology, meaning matches are organized in folders. Don't like the
frames? Just modify the size of both the upper and the left frames. This MSE was created
by researchers at Carnegie-Mellon University. Advanced searching options available:
exact phrase, Boolean operators, fields searching (domain, host, title, URL, etc.) and
more. A jewel for the serious searcher.
Query Server - http://www.queryserver.com/web.htm
Searches an impressive list of 11 SEs - everything important except Google. But don't
worry: Query Server searches Yahoo!, Netscape and AOL, all partially powered by Google.
This is another example of the clustering technology. Highly customizable metasearch
tool. You can modify the appearance of the results page, selecting the search engines, the
amount of results, their timeout, etc. It supports quotation marks to enclose phrases, the
Boolean syntax and parentheses. Very professional.
Infonetware - http://www.infonetware.com
Searches the Web and provides relevant results, organized in topics, in a very clean
interface. This MSE is based in Edinburgh, Scotland and is a very good tool.
Metaseek - http://www.pcdigest.net/metasearch/en/main.shtml
Excellent MSE from Ukraine. Searches major international and local search engines. Besides
the Web you can search images, MP3, FTP files, news and more. You can use
"Phrase" (""), "natural language" processing, Boolean logic
and field searching (by URL, title, site/domain or link). Very nice.
IBoogie - http://iboogie.com
Uses a minimalist design. This MSE "performs intelligent clustering of results".
It searches the Web, the Invisible (Deep) Web, images, video and audio files.
Vinden.NL - http://www.vinden.nl
Searches "the best," providing very good results in a clean interface. This MSE
comes from the Netherlands.
Search Online - http://www.searchonline.info
Uses an excellent selection of search engines and directories. This MSE provides relevant
results in a relatively crowded interface. For each result you can see the search engine
where the hit was found, and its ranking.
Meta Bear - http://www.metabear.com
Provides relevant results from both international and Russian sites. Be sure you type the
query in the "Search The World" box.
Web Scout - http://www.webscout.com
Searches the Web, news, newsgroups, auctions, MP3 files and jobs. This Australian MSE
utilizes the major Ses - except Google - and provides relevant matches in a clean results
argosa:de - http://www.argosa.de
Searches 17 international and local SEs. I suggest you avoid checking the boxes of Acoon,
Abacho, GoClick and ah_ha.com search engines, because they give many irrelevant hits. This
is Germany's first MSE, and provides excellent results organized by relevance, source
(quelle) or title.
Experts Avenue - http://www.expertsavenue.com
Searches different search engines simultaneously for Web pages, auctions, jobs and forums
and provides very relevant results in a neat interface. Enables online language
translation of Web pages. Click on "Translate" and you will be brought to
AltaVista's Babelfish translation service, powered by SYSTRAN.
InfoGrid - http://www.infogrid.com
Provides excellent results in an easy to read layout, despite a very confusing Home Page
crowded and with frames. This MSE searches the "big ones" including Google,
AllTheWeb, Yahoo! and Open Directory. It also searches newswires, auctions, discussion
forums, MP3, FTP files and more. To avoid the frames in the results list select the option
to "Open in the Current Window".
Suchspider.de - http://www.suchspider.de/meta-suchmaschinen
Searches a whopping 100 (!) international SEs and WDs. Google, AllTheWeb, Open Directory,
you name it. You can sort the results by relevance, source or - much better - grouped by
domain name. This "Meta-Suchmachine" is based in Germany.
EmailPinoy - http://www.emailpinoy.com
Sends your query to 15 search engines. Don't use Kanoodle, ah_ha.com and GoClick
pay-per-click search engines, because you'll get irrelevant results. For better results
enclose phrases in quotation marks. This MSE is from the Philippines.
1 SECOND - http://1second.com
Searches a good selection of 14 major SEs and WDs, throws out the duplicates and
summarizes the results in a neat listings page. Use the Advanced Search if you want to
customize the search, especially the timeout of the search engines.
My Prowler - http://myprowler.com
Searches over a dozen search engines, news, images, audio/MP3, music videos, auctions and
various other sites. Compiles the results, weeds out irrelevant matches and provides a
summarized report. It accepts "natural language" query.
Gimenei - http://www.gimenei.com
Use of the "Advanced Search" option is strongly recommended. You can customize
the results page, including my favorite option, "All Results" in one page. This
is a comprehensive and fast MSE based in Manhattan, New York.
Dug Dugi - http://www.dugdugi.com
Queries the major search engines, collates the results, weeds out bad information and
aggregates the results in an ultra-clean layout. For each match you'll get the search
engine and the ranking of the page.
Search 66 - http://search66.com
Groups together pages from the same domain. Beautiful. To avoid SE timeouts, select the
"Speed": "Comprehensive". Obviously, you'll get more results from this
excellent Australian MSE.
Besides the very good MSEs listed above, there are also some
others that are worth a try:
Internav - http://internav.com
NetXplorer - http://www.netxplorer.de (Germany)

ApocalX - http://search.apocalx.com (France)
data Monster - http://www.datamonster.com
Dip Box - http://www.dipbox.com (Sweden)
And last, here are some MSEs you should avoid. Why? Because they
provide very few results, many of them irrelevant:
Excite - http://rd.excite.com/ex/ss.h
Search.com - http://www.search.com
Zworks - http://www.zworks.com
SurfWax - http://www.surfwax.com
2TROM - http://www.2trom.com
Mega Spider - http://www.megaspider.com
Zygit - http://www.zygit.com
Tsunami - http://www.tsunamisearch.com
Multimeta - http://multimeta.com (Germany)
Ariane - http://www.espace2001.com/moteur
2. Pseudo MSEs Type I
The type I "Pseudo" MSE sends the query to the search engines, and then presents
the results grouped BY SEARCH ENGINE in one long, easy to read scrollable list. Be
careful. Based on how many SEs you select, the waiting time can be very long. Some people
might find these MSEs useful, however.
The best MSEs in this category are:
Mall Agent - http://www.mallagent.com/web.html,
which provides results from 38 SEs and WDs,
qb Search - http://www.qbsearch.com/ (from 17),
Better Brain - http://www.betterbrain.com/ (12),
My Net Crawler - http://www.mynetcrawler.com/
NBCi - http://nbci.msnbc.com (11),
Planet Search (Sherlock Hound) - http://www.planetsearch.com/
Rede Search - http://www.redesearch.com/ (8),
1 BLINK - http://www.1blink.com/ (7) and
Search Wiz - http://www.searchwiz.com (6)
Search Fido - http://www.searchfido.com from 4 SEs
3. Pseudo MSEs Type II
There are two types of Type II "Pseudo" MSEs:
a) You type your query one time and then select the search engines. One browser window
will open for each SE selected. The best are:
Multi-Search-Engine.com - http://www.multi-search-engine.com,
which opens 36 windows,
GoGettem - http://www.gogettem.com (30),
Search Bridge - http://www.searchbridge.com
The Info - http://www.theinfo.com (15)
Frame Search - http://www.framesearch.net (15)
b) You choose the SE, type the query IN the SE' form and a new window will open. Every
search engine has its own query form. Many users will find these window-opening MSEs
annoying. The best of this type are:
Alpha Seek - http://www.alfaseek.com,
Dan's No Overhead Search Thingy - http://www.danielc.com/thingy.html,
Express Find - http://www.expressfind.com,
Freeality - http://www.freeality.com/meta.htm
Langenberg - http://www.langenberg.com.
4. Search Utilities (also called Desktop Search Applications)
These are downloadable meta search tools that search multiple search engines. Results are
collated and ranked for relevancy with redundancies removed. They are not free but most of
them have a free trial version available. The price? A few dozen dollars. The most popular
BullsEye - http://www.intelliseek.com/,
Copernic - http://www.copernic.com/,
LexiBot - (formerly know as Mata Hari) - http://lexibot.com,
WebFerret - http://www.zdnet.com/ferret/index.html
First Stop - http://www.firststopwebsearch.com.
Now, you might ask yourself: If MSEs are so good, do we still need the search engines?
Well, it depends. I use a search engine - yup, Google - when I search for general
information. I use a meta search engine when I'm looking for a unique or obscure search
term or if I want to make an in-depth analysis of what's out there on a specific
subject. My suggestion is to find some time and give a test drive to the MSEs; you
might fall in love with these lesser-known search tools. And next time you use your search
engine of choice, remember that there are search tools that can provide you many more
Good luck with your searches!
