First, a definition. Meta Search - A track down tool that queries some track down drives and/or web directories concurrently and returning the results in a single merged items without the double links.
Confused? Let me give you an example. Let's say there is a meta track down drive you have newly found that searchs couple drives, say Google and Yahoo. It tracks down both of these track down drives and afterward returns the merged results to you, without any replicates (results that arise on both engines). Sounds orderly , huh? Well, there are pros and cons with meta tracking down that the user ought be aware of in lead to generate his tracking down as effectual as possible.
Meta tracking down is speedy, and saves extensive time for the user since you may query some drives and directories concurrently alternatively typing in a single query in every track down drive that you expect to receive results. Webmasters will pinpoint meta tracking down extremely valuable in investigating their site's page listings, backlinks, keyword position, etc. Any other profession that is research-oriented would also pinpoint meta tracking down a must-have.
Most, not all, meta searchers do not sanction site submissions. This is because bulk do not continue their have database of page listings. They basically receive results from other track down engines. Because bulk meta searchers query anywhere from 4 to 12 drives and directories concurrently, and not all of them will sanction Boolean tracking down, many meta searchers thus not able to sanction Boolean searching. (Boolean seaching is the exercise of operators such as AND, OR, source tags, and plus/minus symbols.)
THE META SEARCH ENGINES
Meta track down drives come in a assortment of forms. The yardstick meta quester basically queries some drives and returns the results on a single page. Others return results from each drive queried separately, either splitting them on a single page or possibility multiple
browser windows, each containing the results from a dissimilar engine. And another breeding, commonly known as all-in-one track down, also sanctions you to query many dissimilar drives, but just one drive at a time.
