The boolean search serves to narrow the results of a search through operators. There are different recruitment tools where we can do boolean searches such as Job Boards or Scocial Networks.
Why do I need to know how to use it?, to understand in a simple way between using it and not using it, let's think what is a more optimal use of my time? Wash by hand or use the washing machine?
In this use case, we will choose to try basic LinkedIn.
1.Specify words with quotes (")
We use the quotes when we want to find a specific word or phrase and that yes or yes is within the profiles in the search results.
Without using LinkedIn quotes we separte the phrase that is Django and Developer are searched separately, if they exist in the profiles both appear first, but as we go through the pages we will see that they will stop appearing together. With the use of quotes in the search word or phrase they force an explicit result.
2. Forcing two or more words with AND
There are moments where we want two or more words or phrases to appear together on a person's profile, for that we use the AND operator.
3. Choosing between two variables with OR.
We can have different phrases or words that complement each other.
In this example we are searching that the profiles have PHP and they must also have Yii or Zend.
4. Remove unwanted results with NOT.
With the NOT operator we force the search to not include the next word immediately after in the profile.
In this example we are searching Account Executives, as we know there are Account Managers who are farmers and not hunters, so we don't want to consider them, we remove them from our search with NOT manager.
Once the use of operators is mastered, they can be combined as much as desired and you can create booleans as advanced as this:
('Enterprise Services' OR Integration OR Analytics OR 'Managed Services' OR 'Digital Transformation services' OR IoT OR 'Internet of Things' OR 'Big Data' OR Cloud OR Mobility OR 'Software solutions sales' OR 'Software sales' OR 'Solution sales') AND (quota OR YOY OR KPI OR 'Target of sales') NOT manager NOT director.
