Maximizing Recruiting Efficiency with Boolean Searches: A Guide for Recruiters.

Boolean searches are a powerful tool for recruiters that help to refine and optimize their candidate searches, ultimately leading to more efficient and effective hiring. Boolean searches allow recruiters to use specific keywords and operators to create more precise search queries, which will enable them to quickly identify the most suitable candidates for a job opening. In this article, we will discuss how recruiters can use Boolean searches in their hiring process, along with examples of how to use the operators AND, OR, and NOT.

AND Operator (+) :

The AND operator is used to connect two or more keywords in a search query. Using the AND operator returns search results that contain all of the keywords included in the search query. This is useful when searching for candidates who possess specific skills or experience. For example, a recruiter who is searching for a sales executive with experience in both retail and online sales can use the following search query: "sales executive AND retail AND online sales." This will return only the candidates who have experience in both retail and online sales, making the hiring process more efficient.

OR Operator:

The OR operator is used to connect two or more keywords in a search query. Using the OR operator returns search results that contain any of the keywords included in the search query. This is useful when searching for candidates who have experience in different but related fields. For example, a recruiter who is looking for a marketing manager with experience in either social media or email marketing can use the following search query: "marketing manager OR social media OR email marketing." This will return the candidates who have experience in any of these fields, allowing the recruiter to cast a wider net for potential candidates.

NOT Operator (-) :

The NOT operator is used to exclude certain keywords from a search query. Using the NOT operator returns search results that do not contain the keyword that is excluded. This is useful when searching for candidates who have experience in specific areas but want to exclude candidates who have experience in other areas. For example, a recruiter who is looking for a software engineer with experience in Java but not in Python can use the following search query: "software engineer AND Java NOT Python." This will return the candidates who have experience in Java but exclude those who have experience in Python.

Parenthesis ():

Brackets are used to wrap multiple keywords in OR search. This defines the priorities of each segment of the search string. This will come in handy, as most candidate searches are not straightforward and combine various keywords.

Quotation Marks (“ ”)

Quotation marks are used to search for the exact phrase specified. For example, leaving a blank space between ‘product’ and ‘manager’ will provide irrelevant results that contain both of the words ‘product’ and ‘manager,’ but not necessarily together.

Asterisk (*)

The wild card (*) is used to get more variations of the results for the keyword you’re searching for. For example, dev* will provide you with results for both developer and development.

In addition to the basic Boolean operators, there are other operators that recruiters can use to refine their search queries. One such operator is the NEAR operator, which is used to specify that the keywords in the search query must appear in close proximity to each other. For example, a recruiter who is looking for a marketing manager with experience in content marketing and search engine optimization (SEO) can use the following search query: "marketing manager AND content marketing NEAR/5 SEO." This will return candidates who have experience in both content marketing and SEO and who have used both skills together in their previous roles.

A guide to advanced Boolean search strings:

Hiring for rather niche positions or specific skill sets calls for using Boolean strings that are slightly more advanced than the norm.

For instance, you need email addresses of candidates who are working in machine learning or data science, then the search string would be:

Syntax

site: linkedin.com/in (“@gmail.com” OR “@yahoo.com”) (“machine learning” OR “ML” OR “data scientist”)

Still, struggling to wrap your head around it? Take a pen and paper to note the following details:

• Job title of the position you’re hiring for, as well as any other variations that it could have
• Skills that the candidate needs to be proficient in, or any other industry-specific terms
• Platforms you want to run your search on
• Other details that you need like email address, resume, country, etc
• Swap out the text in the below generic search string for what you’ve written down on your list!

Generic Syntax

site: (platform URL) (“The job title you’re recruiting for” OR “enter another variant”) OR “skill 1” OR “other details”

Narrow down your search by using the country name, postal code, diversity preference, company, or natural language in your Boolean search strings, for better results.

Refine your Boolean search strings further

#1 Limit your search to a specific website with the site: search syntax. It is also called x-raying or an x-ray search. It is particularly useful for obtaining profiles with specific skill sets.

Syntax

site:linkedin.com/in (“@gmail.com” OR “@yahoo.com”) (“machine learning” OR “ML”) (“she leads” | “she led”)

You can directly glean the contact information of potential candidates with this search query free of cost instead of using LinkedIn’s InMail service, which is expensive. In this example, “she leads” refers to the natural language we use in a conversation. This query will yield all email addresses containing Gmail or yahoo of women developers who work with machine learning, which are tied to their LinkedIn profile.

#2 Restrict your search to a specific file type with the filetype: search syntax. It could be a resume or a portfolio in a PDF, doc, txt, etc.

Syntax

filetype:pdf resume (engineer OR “software developer”) Boston 2017..2020 -example -sample

This query captures the results of all resumes in a PDF format, from the location specified. The minus operator has been used to eliminate sample resumes from your search. You can also specify a date range; in this case, you don’t want resumes older than 2017 or later than 2020.

#3 Use intitle: search syntax to refine your search to websites with specific keywords in their title. Most candidates upload a resume to all job boards. That could be your keyword to scraping suitable resumes for your requirements

Syntax

intitle:resume (“senior developer” | “lead developer”) India 2018..2020 -sample -example

#4 Use inurl: search syntax to refine your search to websites with specific keywords in their URL

Syntax

inurl:(resume OR CV) python India 2018..2020 -sample -example

Using various combinations of Boolean search strings, it becomes a cakewalk for recruiters to source candidates for a particular job. And not just any candidate, but a candidate who exhibits all the necessary skills for that job. Isn’t that every recruiter’s dream?!

Pros & Cons of Boolean Searches:

Boolean searches are a powerful tool for recruiters that allow them to refine their search queries and find the most suitable candidates for a job opening. However, like any tool, there are pros and cons to using Boolean searches in the recruiting process.

Pros:

1. Precision: Boolean searches can help recruiters find highly specific candidate profiles. By using precise search terms, recruiters can narrow down the pool of candidates to those who match the specific criteria they are looking for.
2. Time-saving: Boolean searches can help recruiters save time when searching for candidates online. Instead of manually searching through hundreds or thousands of resumes, Boolean searches can quickly filter out unqualified candidates, leaving recruiters with a more manageable list of potential hires.
3. Flexibility: Boolean searches are highly customizable, allowing recruiters to adjust their search criteria as needed. This means that recruiters can refine their search over time to find the best possible candidates for their open positions.

Cons:

1. Complexity: Boolean searches can be complex and require some expertise to use effectively. Recruiters may need to invest time in learning how to use Boolean search operators and how to build effective search strings.
2. Limited results: While Boolean searches can help recruiters find highly specific candidates, they can also limit results. If the recruiter's search criteria are too narrow, they may miss out on candidates who possess transferable skills or experiences that could be valuable to the position.
3. Overreliance: Relying too heavily on Boolean searches can lead recruiters to overlook potential candidates who don't fit the specific criteria they are looking for. This can result in missed opportunities to find highly qualified candidates who may not have the exact qualifications the recruiter is searching for.
