The internet is humongous. Finding what you need means that you should select from amongst millions and sometimes trillions of search results. However, no one can claim for sure that you have found the right information. Is the information reliable and accurate? Or would you have to shop for another set of information that is even better? Or say, relevant to the query – While the Internet keeps growing every single minute, the clutter makes it even harder to catch up with, and perhaps, more valuable information keeps getting buried underneath it. Unfortunately, the larger the internet grows, it gets harder to find what you need.
Think of search engines and their browsers to be a set of information search tools that will fetch what you need from the Internet. But, a tool is as good as the job it gets done. While, Google, Bing, Yahoo, and the like are considered more generic tools for Internet search, they perform a “fit all search types job”. The search results throw tons of web pages at you and thus, much harder selections and surely less accuracy.
A simple solution to deal with too much information on the Internet is out there, but only if you care to pay attention – here is a List of Over 1500 Search Engines and Directories to cut your research time in half.
There exists a whole new world of Internet search tools that are job-specific and finds the information you need through filtered and precise search. They subscribe to the same worldwide web and look through the same web pages as the main search engines, but only better. These search tools are split up into Specialized Search Engines and Online Directories.
The Specialized Search Engines are built to drill down into a more accurate type of information. They can collect filtered and less cluttered search results when compared to the leading search engines such as Google, Bing, Yahoo. What makes them unique is their built-in ability to use powerful customized filters, and sometimes it has its database to deliver the type of information you need in specific file formats.
We will classify Specialized Search Engines into Meta-crawlers (or Meta-SearchEngine) and the specialized ones.
Unlike conventional search engines, the Meta-crawlers don’t crawl the web themselves, and they do not build their own web page indexes; instead, they allow search snippets to be collected (aggregated) from several mainstream search engines (Google, Bing, Yahoo, and similar) all at once. They don’t have their proprietary search technology or the large and expensive infrastructure as the main search engines do. The Meta-crawler aggregates the results and displays these on their proprietary search result pages. In short, they usually concentrate on front-end technologies such as user interface experience and novel ways of displaying the information. They generate revenues by displaying ads and provide the user option to search for images, audio, video, news and even more options, simulating a typical search browsing experience.
