Objective Explain Different Types of Searching

Different Types of Searching

One useful feature of information architecture is the ability to search a site. However, not all Web sites need search functionality. If there is relatively little content or if users are all expected to have the same purpose and follow the same paths, then perhaps searching is not necessary. But if a site's content is dynamic, or if there are many different kinds of content, if the site is large, then a search function is useful.

How are searches different?

Since users have different information needs, it is important to decide what search options to offer them. Types of searching can be grouped into four main categories:

Four Main categories of Search

  1. Known item Searching
  2. Existence Searching
  3. Exploratory Searching
  4. Comprehensive Searching
known-item searching, existence searching, exploratory searching and comprehensive searching.
The Slide Show below will take you through an example for each type.



Known Item Search

Where do the answers come from?

Ideally, a complex site with varying user needs will support more than one mode of searching. Searching requires a database serving the site. This database may be owned, designed, and maintained by the company or it may be derived from a more comprehensive, public search engine, such as Excite.

Question: When is it useful to include a search function on your site? When is it not necessary?
Answer: You should include search function if the site has a good deal of information, which is sorted out into many different pages. If site users do not know the organization of your site, it may be quicker for them to find the information through a search engine. It may not be necessary to include a search function if the site is fairly small in size, or if there will be very standard and clear path through the pages of the site. As always, test with sample users.
In the next lesson, you will learn more about information architecture strategies you can use in planning Web sites.
