To facilitate query information, the search engines also provide additional search features (some can be selected in the search engine's Advanced Search Advanced page). Like what:
Word Derivation form Query

When input "thought", if this feature is selected, search engine divided by "thought" as a condition search, but also "think", "thinking" equivalent to the word root query.

Web page snapshots (snap Shot)
The Web page's archive file is pulled directly from the engine database cache, making it easier for users to decide whether to visit the Web site after previewing the content, or to view the original page if the corresponding page changes. Usually the cache is stored in the text part of the Web page, image and other multimedia elements or to be downloaded from the corresponding web site in real time. "Web snapshots" are quite practical compared to other additional features.

Similar to Web page snapshots There is also a "Web Preview" feature (such as the "Sneek-a-peek" of the WISEnut engine) that, when the user chooses this feature, opens a window below the entry to download and display the corresponding page content.

Site Internal Inquiries
When you find a page, the search engine provides the ability to query other pages of the site. Similar to "site:", "Host:" and other commands.

Horizontal related Query
When a user finds a page of interest, the search engine provides the functionality of the other pages that are similar to the query content (not limited to the same site). Typically, the link to the "Errors Pages" or "more results as this" is given after the information entry.

Concept extension Query
When you query with a keyword, the search engine lists other search terms in the relevant field for you to choose from. For example, enter "Furniture", which lists the relevant information categories such as "Outdoor furniture", "Patio furniture", "office furniture", and so on.

In addition to the above features, search engines are now starting to provide classified search, such as news search, image search, newsgroup search, flash search and so on. The original intention of the search engine is good, are all for the convenience of the user, as to which useful and what is useless is completely to see a person's preference. In our opinion, search engine is only a tool of our information query, unless you want to become an information search expert, otherwise master the basic search skills and use it skillfully enough to meet our daily needs.
