Boolean operators to search more efficiently on the World Wide Web

Many times we use the search engines following our habitual inertia and we put directly in the search box the terms or keywords to look for. This usually gives us a torrent of miles or millions of results that do not obey what we are looking for, we can avoid it by using the Boolean search and obtain much more precise results.

When users searching for search engines can use more precise search operators, some search engines allow the use of these Boolean operators that establish simple relationships between the search terms. These operators are perfect if we want to refine our searches and also its use is not complex. Employ Boolean operators, make your information searches more sophisticated and effective.

Internet users can use a search engine to search results of a specific topic on the internet. The most popular search engines have techniques to perform more precise search results, these techniques are the use of Boolean operators. By using the Boolean operators we can restrict or highlight words in a phrase in order to make more precise searches.

AND, &: It is used to join different kinds of concepts of the question.
Cars AND Motorbikes.

Or, | : has the ability to connect words and get results related to the two words.
Red Cars OR Blue Cars

+: This operator is used to find the exact word in a document.

NOT, -,! : This operator excludes a specific term in a phrase. The next case will omit the word Java.
Algorithms in -Java

«»: This operator is used to search for exact phrases. Very used to look for names of institutions or people.
«How to program»

*: Will return any result that begins with the word that precedes the wildcard.
Program *, we can obtain results like: Programming, Programmer.

. : the point performs almost the opposite of the wildcard. Preventing a word from spreading.
Program we will obtain only results limited to the word Program.

(): Will search the results enclosed in parentheses first.
(Java or C ++) programming in PHP

NEAR: Shows those results that include the two terms together (less than 10 words away) in the same field regardless of whether «Jobs» goes before or after «Java».

We can find more Boolean operators like: XOR, FAR, ADJ.
