Search Operators

General Boolean operates on true or false

Boolean in sourcing run on a variety of operators

Most basic: AND, OR, & NOT

AND

OR

OR connects joins different ways to describe a concept (“objective c” OR cocoa)

OR can also be used to connect two different concepts (mysql OR tsql)

Typically OR statements enclosed in parenthesis ( A OR Z)

NOT/-

Real World

Java engineer with framework experience, who has not worked for company ZYX

(java OR j2ee) AND (spring OR hibernate) NOT zyx

Best practices

Keep every string in one place (1 document, cloud stored)

Write strings in simple word editors ie Notepad (PC) or Text Editor (Mac)

Don’t write strings in Word

Thursday, September 5, 2013

Why Not Word

Word has a feature call Smart Quotes “”

Job boards and other platforms sometimes malfunction when Smart Quotes are in a query

Simple text files can be read every where and work everywhere

The Perfect Boolean String

No such thing

A string is perfect when the person you found using it is hired

Always re-evaluate strings in a search

Thursday, September 5, 2013

Bad Boolean Strings

java OR android developer

java OR “android developer”

php OR python AND lamp

(php OR python) AND lamp

lamp java net iphone
