ENGINES
What:
When you use a search engine to search the web, you are searching
only the web pages and web objects (i.e. PDF files) that the
search engine has identified at a given point in time.
You are not seeing everything that is available to you on the web
no search engine can do that. You are not searching the web in
"real time" - only a given point in time.
How:
Search engines use software called "spiders" and "crawlers" to
routinely scour the web to identify and index web pages. The
software used by each search engine works a bit differently.
Consequently, the same search conducted with different search
engines will yield different results. You may want to try your
search in more than one search engine and compare results.
Why:
Why use a search engine, as opposed to a directory?
Size:
when you use a search engine, you are searching
through billions of web pages.
Searching for Specific Information:
If you are looking for very specific or complex
information, try a search engine. Advanced search
features will allow you to refine your search and
improve your results.

WHAT IS A
SEARCH ENGINE?
Search engines are programs that search documents for specified
keywords and returns a list of the documents where the keywords
were found. A search engine is really a general class of programs,
however, the term is often used to specifically describe systems
like Google, Bing and Yahoo! Search that enable users to search
for documents on the World Wide Web.
Web Search Engines
Typically, Web search engines work by sending out a spider to fetch
as many documents as possible. Another program, called an indexer,
then reads these documents and creates an index based on the words
contained in each document. Each search engine uses a proprietary
algorithm to create its indices such that, ideally, only meaningful
results are returned for each query.

INFORMATION
RETRIEVAL
(IR)
Information retrieval (IR) is the activity of obtaining information
resources relevant to an information need from a collection of
information resources. Searches can be based on metadata or on
full-text (or other content-based) indexing.
Automated information retrieval systems are used to reduce what has
been called "information overload". Many universities and public
libraries use IR systems to provide access to books, journals and
other documents. Web search engines are the most visible IR
applications.

INDEXING
Search engine indexing collects, parses, and stores data to facilitate
fast and accurate information retrieval. Index design incorporates
interdisciplinary concepts from linguistics, cognitive psychology,
mathematics, informatics, and computer science. An alternate name for
the process in the context of search engines designed to find web pages
on the Internet is web indexing.
Popular engines focus on the full-text indexing of online, natural
language documents. Media types such as video and audio and graphics
are also searchable.
Meta search engines reuse the indices of other services and do not store a
local index, whereas cache-based search engines permanently store the index
along with the corpus. Unlike full-text indices, partial-text services
restrict the depth indexed to reduce index size. Larger services typically
perform indexing at a predetermined time interval due to the required time
and processing costs, while agent-based search engines index in real time.
