Using Boolean Search for accurate search-results

Author: Manish Shrivastava

The Boolean Search is developed on a Mathematical logic developed by Charles Boole. In Inte rnet Search Engine Optimization, the concept of Boolean searching is widely used where most of the search engines and online databases support the search mechanism using Boolean operators. Boolean searches can help in finding the desired information eliminating unnecessary details.

The Boolean Search concept is simple and effective. The concept is mainly based on three operators. These are:

Boolean AND The AND operator when used in a search term, returns result containing both the keywords. This can be illustrated with the following example:

Club AND Football

The above search term will return all pages which include both the keywords Club and football . However, it will not show the pages containing only Club or football . Search engine optimization specialist often suggests to use AND operator to eliminate undesired results from searched information.

Boolean OR The Boolean OR operator will return all the pages with at least one of the keywords. For example:

Club OR football

The above search condition will return all those pages where at least the keyword Club or football can be found. Thus, the result will include all pages with either the keyword club or football or both.

Boolean NOT The Boolean NOT operator helps in removing a certain keyword from the search. The NOT operator makes the search engine to include pages containing the first keyword and exclude all pages containing the second keyword. For example:

Club NOT football

Here, the search result will include all the pages with the keyword Club and the same time the result will not include any page with the keyword football . This methodology actually helps in filtering information containing closely related keywords.

Most of the sear ch engine optimization companies suggest on formulating a search strategy using the Boolean operators. These are:
