Explain the use of the following search operators AND

Explain the use of the following search operators – +, - , “ “, *, AND, NOT, OR

Solution

(boolean operators are used for connection and also used to define a relation between your search terms which we search .boolean search is one type of search that makes allow for users to combine the keywords which he typed with oparators like AND, NOT and OR to generate more related results.Boolean operator should be used only in capital letters or else they will be treated only as terms.

AND:

suppose when we are searching for results that include both the term before and the term after taht the operator. For example

query from name1 AND to name 2 returns every messages that were sent from name1 to 2 nd name.

OR:

when we are searching for results that include both the term before and the term after operator or even both. For example:

The query from name1 OR to name 2 returns every messages that were sent from name1 to 2nd name.

NOT:

when we are searching for result that does not included after the operator.

example:

The query from name1 NOT to name 2 returns every messages that were sent from name1 to anyone except 2nd name.

operator(*): it is an wildcard operator.it uses at end of the search term for unknown wildcard term.

the wildcard operator is supported only if it is at end of the term.

operator(\"\"):it is only used for yout to specify the excat phrase we would want.

for example:where is \"john cena\"

operator(-):

this opeator name is hyphen.for example when we used hypen it states what ever is after hyphen it should be excluded.

(+,-) opeators comes under punchuations .if we use or we dont use the punctuations also result may or may not be improved.

(+:)it searches for postive(+)pages

and also like grops(blood)

(-): This is useful for words haviang multiple meanings for example:swift the car brand and swift the bird.
