A search box, search field, or search bar is a graphical control element seen in computer applications and websites such as file managers and web browsers. A search box is often a single-line text box or a search icon (which transforms into a search box on click action) that accepts user input to be searched for in a database. On most online pages, search boxes are used to allow users to enter a query that will be sent to a Web search engine’s server-side script, which will search an index database for entries that include one or more of the user’s keyword research.

A search button (sometimes just a magnifying glass icon) is usually seen next to a search field to submit the search. The search button, on the other hand, may be eliminated since the user may submit the search by pressing the enter key, or the search can be submitted automatically to show the user with real-time results.

The search box is an important aspect of website design for content-rich websites since it is a vital part of the site search operation. Site search is more prevalent on certain websites than on others. Search boxes, and hence site search, are commonly used as a key navigation tool in e-commerce.

Characteristics That Are Common

A search box may be accompanied with a drop-down list to show users with previous searches or search recommendations, depending on the implementation. Other tools, such as autocomplete, search recommendations, a spelling checker, and so on, may be included in search boxes to assist users. Drop-down menus or other input controls are frequently used in conjunction with search boxes to allow the user to narrow the search or select the sort of information to be searched for.

In certain circumstances, as users type search phrases, the results of such searches appear in the content section, which updates in real time. However, if the page chooses this method of displaying results to consumers, the loading time will be longer, which may cause lagging or a browser crash. As a result, it is unsuitable for small and medium-sized websites.

Persistent connections are used in modern search box implementations to achieve both a low-latency search experience and increased bandwidth. Huge, search-intensive online applications, on the other hand, require a scalable server capable of handling a large number of concurrent persistent connections. Such servers are already available. For example, with a mean round-trip latency of 11.82 milliseconds, a single instance of MigratoryData’s WebSocket server could handle 240,000 autocomplete requests per second from 1 million concurrent users.
