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 know as 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 relevant. MSEs can be used by Webmasters
to find their site's presence, rankings and
link popularity in the major SEs.
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 used.
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.
The following 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,
the speed of their searches and others.)
ez2www [ ez2www.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 [ 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 [ 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 [ 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 [ 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 [ 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 [ www.vinden.nl ]
Searches the best providing very good results in a
clean interface. This MSE comes from the Netherlands.
Search Online [ 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 [ 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 [ 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 list.
argosa:de [ 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 [ 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 [ 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
"Open in the Current Window".
Suchspider.de [ 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 [ 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 [ 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 [ 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 [ 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 [ www.dugdugi.com ]
Queries the major search engines, collates the results,
eliminates 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 [ search66.com ]
Groups together pages from the same domain. Beautiful.
To avoid SEs 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 [ internav.com ],
NetXplorer [ www.netxplorer.de ] (Germany),
Aaise [ www.aaise.com/meta ],
Metengine [ www.metengine.com ] (Antigua),
One2Seek [ www.one2seek.com ],
Ithaki [ www.ithaki.net ],
Fossick [ www.fossick.com/Search.htm ] (Australia),
Pandia [ www.pandia.com/powersearch/index.html ]
(Norway),
meta EUREKA [ www.metaeureka.com ] (Netherlands),
Widow [ www.widow.com ],
VROOSH! [ www.vroosh.com ] (Canada),
Meta 360 [ meta360.com ],
7 Meta Search [ 7metasearch.com ],
Metor [ www.metor.com ] (Germany) and
Ixquick [ www.ixquick.com ].
The following is a list of some unimpressive
meta search engines. These MSEs do not provide the breadth
of coverage offered by the sites recommended above.
Each of these has its own flawed characteristics, but
generally they are old and have not kept up with
the latest capabilities or they suffer from too many
functional problems.
Metacrawler [ www.metacrawler.com ],
Dogpile [ www.dogpile.com ],
C4 (formerly Cyber 411) [ www.c4.com ],
Mamma [ www.mamma.com ] (Canada),
Pro Fusion [ www.profusion.com ],
moonmist [ www.moonmist.info ] (UK),
Bytedog [ www.bytedog.com ] (Canada),
il motore [ www.ilmotore.com ] (Italy),
METASEEK.NL [ www.metaseek.nl ] (Netherlands) and
ApocalX [ search.apocalx.com ] (France).
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 [ www.mallagent.com/web.html ],
which provides results from 38 SEs and WDs,
qb Search [ www.qbsearch.com/ ] (from 17),
Better Brain [ www.betterbrain.com/ ] (12),
My Net Crawler [ www.mynetcrawler.com/ ] (12),
NBCi [ nbci.msnbc.com ] (11),
Planet Search (Sherlock Hound)
[ www.planetsearch.com/ ] (10),
Rede Search [ www.redesearch.com/ ] (8),
1 BLINK [ www.1blink.com/ ] (7),
Search Wiz [ www.searchwiz.com ] (6) and
Search Fido [ www.searchfido.com ] from 4 SEs and WDs.
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 [www.multi-search-engine.com]
which opens 36 windows,
GoGettem [ www.gogettem.com ] (30),
Search Bridge [ www.searchbridge.com ] (24),
The Info [ www.theinfo.com ] (15) and
Net Depot [ www.netdepot.org ] (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 [ www.alfaseek.com ],
Westlaser [ www.westlaser.com/ ],
Dan's No Overhead Search Thingy
[ www.danielc.com hingy.html ],
Express Find [ www.expressfind.com ] and
Freeality [ www.freeality.com/meta.htm ] .
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 are:
BullsEye [ www.intelliseek.com/ ],
Copernic [ www.copernic.com/ ],
LexiBot (formerly know as Mata Hari) [ lexibot.com ],
WebFerret [ www.zdnet.com/ferret/index.html ] and
WolfBot [ www.wolfbot.com/ ].
Conclusions:
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 relevant results.
Good luck with your searches!
