DIFFINATION OF SEARCH ENGINES
The search engine is programs that are created for specified keywords search and return a list of websites where the keywords were found. Although search engines are a general class of programs, they often used to describe specific systems such as Google, Alta Vista and Excite; the user can find documents on the World Wide Web and Usenet newsgroups.


TYPES OF SEARCH ENGINE
  1. Individual Search
  2. Meta Search
Individual: These are search engines who have their own database of websites data where they search and show results .
Meta: Meta-seekers do not compile databases. Instead, they look for the databases of multiple sets of individual engines simultaneously.
A meta-search engine items for more than one user each search engine and query their databases of web pages and receive results from all search engines. We could thus save a lot of time by initiating the search at a single point and avoids the need to use and learn several separate search engines. This can be very helpful if we are looking for a wide range of results.



SEARCH ENGINE PERFORM

Search engines get their databases with "spinning" or "spam" (boots) to carry the web space from link to link crawl, identification and browsing through the pages. Pages without links to other pages by spinning missing. Once the spiders get to a site, they are typically index most of the words on the publicly accessible pages on the site. Owners of web pages to search engines for their URLs to "Crawling" and inclusion in their databases. Each time you search, find using a search engine, you get the engine to the index of sites that match your keywords and phrases which in the texts of the documents in a database scan engine.
IMPORTANT NOTE:

It is important to remember that if you have a search engine, you are not searching on the Web as it exists at this moment. Are you actually looking for a part of the web in a fixed index created at an earlier date captured.
SPEED OF SEARCH ENGINE

It is hard to say. Spiders regularly look to the web-page index to change it to return. If changes occur, the index is updated to reflect new information. However, the update process for some time, depending on the frequency of the spinning drive their laps and then how quickly the information they collect to the index is added. Until a page has been both "spidered" AND "indexed, " you will not be able to access new information.

CONS:

On the negative side will be the biggest number of words by search engines, the probability of returning hundreds of thousands of responses indexed for easy searching. Remember, they re very large documents in which your keyword appears once. Many of these responses are not relevant to your search.
SIMILARITY OF SEARCH ENGINE
Search engines use software for some of its index of key words, phrases, look for game, present their findings with your in a kind of relevance ranking. Although the software may be similar no two search engines are exactly the same in terms of size, speed and content, no two search engines use exactly the same classifications that not all search engines, which has exactly the same search options. Therefore, the search is different on every engine you use. The difference is perhaps not much, but could be significant. Recent estimates put search engine overlap at approximately 60 percent and unique content to about 40 percent.
HOW DO SEARCH ENGINES RANK WEB PAGES

In the rankings of web pages, search engines follow a certain set of rules. These can vary from one engine to another. Your goal, of course, the most important pages are to return to the top of their list. You can find the location and frequency of keywords and phrases in the document from a Web page and sometimes in the META tags.
