What Is MetaCrawler and How Does It Work

MetaCrawler is a search engine aggregator that collects results from multiple search engines and presents them in a single interface. It was launched in 1995 by O'Reilly & Associates.

MetaCrawler's main goal is to provide users with a comprehensive search experience by aggregating results from various search engines, including Altavista, Yahoo!, and Lycos.

This approach allows users to search multiple engines at once, increasing the chances of finding relevant results. MetaCrawler's search results are also often more comprehensive than those of a single search engine, making it a useful tool for researchers and students.

In addition to its search functionality, MetaCrawler also provides a feature that allows users to specify the search engines they want to use and the order in which they want to search them.

MetaCrawler was first developed in 1994 as a PhD project at the University of Washington by Erik Selberg and Professor Oren Etzioni. It was originally created to provide a reliable abstraction layer to web search engine programs in order to study semantic structure on the World Wide Web.

MetaCrawler was launched on July 7, 1995, and initially logged over 7,000 search queries per week, accessing six services: Galaxy, InfoSeek, Lycos, Open Text, WebCrawler, and Yahoo. By late 1996, there were over 150,000 queries per day.

MetaCrawler's owners were unable to determine a reasonable business model, so they sold it to Go2Net in January 1997, which later became part of Excite after InfoSpace acquired Go2Net in July 2000. MetaCrawler was later merged into Zoo.com in 2014, and then relaunched as its own search engine in 2017 under the ownership of System1.

MetaCrawler was founded in 1994 as a PhD project at the University of Washington. The founders, Erik Selberg and Professor Oren Etzioni, created a metasearch engine that combined the results of several other search engines to provide users with a comprehensive overview of information on the Internet.

The innovative approach of MetaCrawler relied on using the search results from different search engines instead of creating a separate index database. This allowed users to access a wider range of results and increased the likelihood of finding relevant information.

By the end of the 1990s, MetaCrawler was already registering thousands of search queries per week. This was a significant milestone in the history of MetaCrawler, demonstrating its popularity and effectiveness.

MetaCrawler's unique strategy was closely linked to academic research, revolutionizing the way information is searched and found on the World Wide Web.

MetaCrawler.com is a search engine that aggregates results from multiple sources, including reputable search engines. However, users should be cautious when using its services, as the sponsored results can lead to dubious software installation methods or misleading websites.

The search engine has a history of redirecting users to suspicious websites, including fantastigames.metacrawler.com, which is a sub-domain of MetaCrawler.com. If you notice your browser redirecting to this site, it's likely that your PC is infected with redirect malware.

Using legitimate antivirus and anti-spyware programs can help protect your computer from such incidents. Keeping your installed programs and operating system up-to-date is also crucial in preventing infections.

Computer users should be aware of the potential risks associated with MetaCrawler.com and use it with caution.

We're designed to work in a way that makes it easy for you to find what you're looking for. MetaCrawler aggregates results from multiple search engines, giving you a broader range of results and increasing your chances of finding exactly what you're looking for.

Our architecture is modular, which means we have different components that work together to provide you with the best possible experience. The main components are the User Interface, the Aggregation Engine, the Parallel Web Interface, and the Harness.

The User Interface is where you enter your queries and options, and it translates them into the right parameters for the Aggregation Engine. The Aggregation Engine is where the magic happens, obtaining initial references from each service, post-processing them, eliminating duplicates, and collating and outputting the results back to you.

MetaCrawler is a Software robot that aggregates Web search services for users, presenting them with a single unified interface.

Users enter queries, and MetaCrawler forwards those queries in parallel to sundry search services, then collates the results and ranks them into a single list.

The key idea is that the MetaCrawler allows the user to express what to search for and frees the user from having to remember where or how.

MetaCrawler has several features that enable users to obtain high-quality results, such as instructing the bot to find pages with either all of the words in their query or any of the words.

Users can also specify if a word must or must not appear in any reference returned, as well as if a reference comes from a particular geographic or logical location.

To accomplish its goal, MetaCrawler must be adept at several tasks, including taking user queries and formatting them appropriately for each search service.

MetaCrawler must also be able to correctly parse the results and aggregate the results from the other services, and analyze the results to eliminate duplicates and perform other checks to ensure quality.

MetaCrawler differs from traditional search engines by aggregating results from multiple search engines, like having a team of search engines working together to deliver a broader range of results.

Our team designed MetaCrawler in a modular fashion, allowing for easy modification and scalability. This approach has proven to be highly effective in adapting to the ever-changing web landscape.

The main components of MetaCrawler's architecture include the User Interface, the Aggregation Engine, the Parallel Web Interface, and the Harness. These components work together seamlessly to provide a robust and efficient search experience.

The User Interface is responsible for translating user queries and options into the appropriate parameters, which are then sent to the Aggregation Engine for processing. This component is where most of the sophisticated features of MetaCrawler reside.

The Aggregation Engine is responsible for obtaining initial references from each service, post-processing the references, eliminating duplicates, and collating and outputting the results back to the User Interface. This process ensures that users receive accurate and relevant search results.

The Parallel Web Interface is responsible for downloading HTML pages from the web, including sending queries and obtaining results from each search service. This component plays a crucial role in providing a comprehensive search experience.

The Harness is the crux of MetaCrawler's design, where service-specific information is kept. It receives control information detailing which references to obtain and formats the request properly to send to the Parallel Web Interface.

Scalability is a crucial aspect of any online service, and our solution is designed to handle a growing user base without breaking the bank.

The load on our servers scales linearly with the number of requests per day, which means that as more people use the service, our infrastructure needs to keep up.

To achieve this, we're using implementations resident on users' machines, which allows us to scale without needing to add more machines.

This approach puts the responsibility on each user to handle their own network and computational requirements, freeing up our servers to focus on providing the service.

Every user only needs to contact the server periodically to obtain updated service lists and other new information, which reduces the strain on our resources.

MetaCrawler's journey was marked by a significant transformation in 2014 when it was integrated into Zoo.com, another search service operated by InfoSpace.

This integration brought MetaCrawler under the umbrella of a company that specialized in search technologies, but it was short-lived.

In 2016, InfoSpace was acquired by OpenMail, which later changed its name to System1, and this led to another transformation for MetaCrawler.

System1 decided to revitalize MetaCrawler as an independent search engine, returning to its original vision of a metasearch-based information source.

This revitalization underscored the continued importance and potential of MetaCrawler in providing information on the internet.
