MrMeta.com is a "Xpert" metasearch engine — every time you type in a
query MrMeta simultaneously searches a variety of engines, directories, and
deep content sites, properly formats the words and syntax for each,
compiles their results in a virtual database, eliminates duplicates, and
displays them in a uniform manner according to relevance. It's like using
multiple search engines includes google, msn, yahoo search, altavista,
ask, A9, and many others, all at the same time. |

Every time you type in a query at a metasearch engine, they search a
series of other search and content sites at the same time, compile their
results, and display them either by source or by integrating them in a
uniform manner, eliminating duplicates, and resorting them according to
relevance. It's like using multiple search engines, all at the same
time.
By using a metasearch engine, you get a snapshot of the top results from a
variety of search engines (including a variety of types of search
engines), providing you with a broad scope of information. Metasearch
engines are tolerant of imprecise search terms or inexact use of
operators, and tend to return fewer results, but with a greater degree of
relevance. They're best used when you've got a general search, as
metasearch engines return broad results. Instead of returning every
possible result that contains your search term, metasearch will return the
most trusted results on the Internet for your search. Metasearch engines
also allow you to compare what kinds of results are available on different
engine types (indexes, directories, pay-for-placement, etc), or to verify
that you haven't missed a great resource provided by another site, other
than your favourite search engine (acting as a backup). Overall, they're a
great way to save time and find exactly what you're looking for!
Our Ranking Algorithm: rSort
rSort
works like a voting system for search results. The search engines
MrMeta.com queries often return duplicate results. Instead of simply
eliminating the duplicates as many metasearch engines may do, we use this
information to rank our results. Each duplicate search result is
considered a 'vote' for that result. Pages with the highest number of
votes go at the top of our result set (for the mathematicians in the
audience, the method of voting we use is a simplified version of the
"Condorcet Method", named after the mathematician Marquis de Condorcet who
invented this voting procedure in the 18th century). One of the big
advantages of this ranking method is the elimination of search engine
spam.
Spammers often have difficulty spamming more than one engine at the
same time, as different spamming methods must be used for each search
engine. Spam results will tend to receive fewer votes from multiple
sources. A spammer may have top ranking on one search engine, but they
won't achieve it on MrMeta unless they're able to spam ALL of our sources,
an insurmountable task for even the best spammer.
Here are some interesting stats about rSort:
- On average, the Rsort algorithm places the first 8 results on
MrMeta.com (i.e. there are, on average, 8 results with duplicates).
- The Rsort algorithm affects the ordering of our search results
on average about 80% of the time (i.e. there is at least one
result with duplicates for 80% of searches).
- The two engines that vote the same the most often are MSN and
Teoma. Interestingly, on the average query, MSN and Teoma results
match up only about 7% of the time, meaning 93% of the results
they return are unique.
