3. INTRODUCTION
 A database is an organized collection
of data, today typically in digital form.
 The concept of database has evolved since
the 1960s to ease increasing difficulties in
designing, building, and maintaining
complex information systems.

4. GENERAL DATABASE
 The World Wide Web can be thought of as a
database, spread across millions of independent
computing systems.
 Web browsers "process" this data one page at a
time, while web crawlers and other software
provide the equivalent of database indexes to
support search and other activities.
 The examples of general databases search
engines are:
 GOOGLE
 YAHOO
 SLIKK
 SURF CANYON
 HAKIA

5. GOOGLE
 Google is the leading search engine used to
search the web for information.
 It searches its database for relevant
information, that satisfies the users query.
 It uses the simple search and advanced
search features to search and retrieve the
relevant information in the form of websites
stored on its server.

6. GOOGLE SEARCH STRATEGY
 In simple search, the queries are accepted as
a simple text, and the user's text are broken
up into a sequence of search terms, which are
usually words that are to occur in the results.
 It has an „I am Feeling Lucky‟ icon, which
leads the user to the first search
result, bypassing the search engine results
page.

features where the user can find pages by

9. GOOGLE SEARCH STRATEGY
‣ Results can also be found using operators
such as
 Minus sign (-) for excluding the term from
the search result.
 Tilde sign (~) to search for synonymous
terms. It is used to include similar words.

unknown or "wildcard" term.

10. GOOGLE SEARCH STRATEGY

page, blocking unwanted results).

23. SURF CANYON HOME PAGE

24. SURF CANYON
 Surf Canyon is a browser extension that sits
atop search engine sites like Google, Yahoo!
and Bing.
 Surf Canyon develops "real-time personalized
search," a technology that disambiguates the
user's intent post-query, and, in real
time, brings forward to page one the relevant
results that might otherwise remain buried.
 It has provision for refinement of the query
typed in the search box.

25. SURF CANYON
 By transforming static lists of links into
dynamic search pages that automatically re-
rank results, users are able to more quickly
and easily find pertinent information buried
among the irrelevant results, significantly
accelerating the search process.
 It also provides real time recommendations
based on the users activity.
 On clicking the search result, it is directly
opened in a new tab.

26. HAKIA HOMEPAGE

27. HAKIA
 The Hakia search engine uses the semantic
search technology for searching.
 Semantic search technology is based on a
computerized system that understands
content and query similar to how the human
brain processes natural languages.
 Semantic search systems match concepts and
their meaningful variations

28. HAKIA
 It is focused on bringing quality results in all
segments including Web, News, Blogs, hakia
Galleries, Credible Sources, Video, and
Images.
 Some segments are processed by hakia's
proprietary core semantic technology
called QDEXing (Deep Semantics)
 Other segments are processed by
hakia's SemanticRank technology using third
party API feeds (Surface Semantics).

29. COMPARISONS
 Google allows the user to categorize the
search results as visited and not visited
pages, websites translated from foreign
languages and shows the reading level of the
terms of search.
 The Slikk search engine allows the user to
view and open the results on the same page.
One can see the webpage without going to a
new tab.

30. COMPARISONS
 Slikk also allows the user to view all the open
search results in one window
simultaneously, so that the user does not
keep shuffling from one window or tab to the
other.
 Surf canyon provides real time
recommendations based on the users
activities.
 It brings to the front the search results that
are related to the links the user has opened.

31. COMPARISONS
 Hakia, unlike other search engines uses
semantic search strategy, that processes the
query and understands the content instead of
matching the occurrence of words or
symbols.
 It matches the concepts and their meaningful
variations.
