## When to Use

All technologies that include forms.

## Description

Providing a search function that searches your Web pages is a design strategy that offers users a way to find content. Users can locate content by searching for specific words or phrases, without needing to understand or navigate through the structure of the Web site. This can be a quicker or easier way to find content, particularly on large sites.

Some search companies offer sites free access to their search applications. Search engines are available that can be installed on your own server. Some web hosting companies offer search scripts that customers can include on their web pages. Most services also offer paid versions of their tools with more advanced features.

Implementing a search function that will spell-check the terms, include different endings for the terms (stemming), and allow for the use of different terminology (synonyms) will further increase the accessibility of the search function.

The search functionality is added by either including a simple form on the Web page, usually a text field for the search term and a button to trigger the search or by adding a link to a page that includes a search form. The search form itself must be accessible, of course.

Techniques that are used to optimize search engine results for external searches also support internal search engines and make them more effective: use keywords, META tags, and an accessible navigation structure. Search sites provide guidance on how to create content that is optimized for search, for instance Google Webmaster Guidelines, and Yahoo! Search Content Quality Guidelines.

## Examples

### A Shopping Site

A shopping site organizes its products into different categories, such as women's clothes, men's clothes, and children's clothes. These have subcategories, such as tops, pants, shoes, and accessories. Each page also contains a search form. Users can type the product number or product description into the search field and go directly to that product, rather than needing to navigate the product categories to find it.

### A Help Center

A Help Center contains thousands of pages of Help information about a company's products. A search form allows users to search just the Help Center pages to find articles that contain the search terms.

## Tests
