Boolean search techniques help recruiters refine and target searches for job candidates using specific keywords and operators. While Boolean search is useful in many fields, this article explains how Boolean search works in the recruitment context.
What Is Boolean Search?
A Boolean search uses words known as operators to help users find search results faster. The Boolean operators AND, OR, and NOT can be added to phrases or words to help broaden or narrow down search results. When conducting a Boolean search, users are telling the database exactly which results they wish to be returned and which results they deem irrelevant. Different operators have different functions and, as such, can benefit employers and researchers in different ways. Operators can also be used in conjunction with one another to increase the accuracy and exclusivity of results.
Researchers and recruiters should use AND’ to specify the exact combination of results they wish to receive. When using AND, the database will only produce results that match and are applicable to both terms. As a result, users can eliminate any potential for one-sided or unbalanced search engine results. The AND operator is particularly advantageous for employers looking to find a candidate who meets multiple specificities outlined in the job criteria. If a user were to search the terms ‘Designer’ and ‘Editor’ using the operator AND, then the results produced would only identify professionals with both skill sets.
The operator OR can be used to broaden search results. Here, the results produced will be applicable to either specified term or both at the same time. Using the operator OR, researchers can easily compare topics and subject matters. This is particularly beneficial for employers who do not know which skill set to prioritize or who are open to a wider range of candidates.
Conversely, the operator NOT is used to narrow down results. Here, users can define the results they wish to see and exclude others that they deem irrelevant or unuseful. The OR operator is particularly useful in separating terms that are often seen together. If a user wished to find results pertaining solely to detached houses and not apartments, they could use the operator NOT to ensure that all results were exclusively related to houses.
Additional methods of conducting a Boolean search include using parenthesis (brackets) and using quotations. The parenthesis Boolean operator allows users to designate priority status to certain terms. By using brackets, users can define which results they need to find and which results are less important. This method broadens the scope of results but equally ensures that all results produced are relevant and appropriately streamlined.
When using the quotation operator, only results, including exact phrases will be produced. This is particularly helpful if users are looking to find the source of information or words or are hoping to confirm something they have read/heard.
How Does a Boolean Search Help in Recruitment?
A successful recruitment process will ensure that candidates are only chosen based on their skills, qualifications and company fit. Finding candidates with desirable skill sets is crucial to increasing both employee productivity and employee satisfaction rates. Boolean searches enable employers to specify the criteria that candidates must meet in order to be considered for a job position. Competence with Boolean operators is increasingly important in recruiter education.
The operator AND can be used by employers to ensure that the candidate chosen is competent in two areas. Candidates who are skilled in multiple fields or who have complementary skill sets can prove very beneficial for employers looking to optimize the efficiency of company operations and save time during the recruitment process. An employee who is qualified in both design and editing will save companies the need to hire and onboard a further individual solely for editing purposes. Employers can also use the AND operator to screen out employees with insufficient levels of experience. This ensures that selected candidates are qualified, competent and have proven expertise relating to the relevant job position.
Employers can additionally use the operator OR to define the parameters of results they wish to see. This operator helps employers identify a range of potential candidates, ensuring that no qualified candidate is overlooked during the screening process. Employers can use the OR operator to fill vacancies where more than one skill set is required or advantageous. Though vocational professions such as medicine and teaching require candidates to have specific qualifications related to that profession, many jobs can be performed by candidates with less exclusive skill sets. Transferable skills refer to abilities that can be used in and are beneficial to more than one profession or role. The OR operator allows employers to identify candidates with desirable ‘transferable skills.’ Moreover, businesses may find that the diversity created through a less exclusive recruitment process may be more beneficial to company morale and productivity.
When using the operator NOT, employers can ensure that only candidates with the specified skill sets, qualifications, or relevant experience are identified. Employers can use the NOT operator to eliminate certain skill sets that they find unuseful or irrelevant to the particular job role. Suppose employers have been disappointed by candidates with specific skill sets in the past or have noticed a pattern relating to candidates with certain qualifications. In that case, they may wish to use the NOT operator. Here, candidates can ensure that all recruitment decisions are strategic and conducive to the company’s success. Additionally, the recruitment process for job positions that are easily conflated or confused with other roles can be simplified through an exclusive search approach.
The parenthesis operator enables employers to prioritize the results they most wish to see. This can be beneficial for employers who are looking for candidates possessing particular skills but who are equally open to candidates with additional abilities and qualifications.
Tips for Using Boolean Search Effectively
1. Create More Specific Queries
Unlike the majority of search engines, which produce results based on what they believe users wish to find, Boolean searches allow users to create more specific search queries. When combining keywords and operators, employers can ensure that the search results produced are accurate, useful, and relevant.
Employers and researchers alike can optimize their search using multiple Boolean operators. By combining the operators AND and NOT, users can ensure that the results produced account for both groups of specified keywords. Many sites will also include advanced search options where users can specify the importance of their combined operators and keywords. It is important to note that search engines tend to prioritize AND’ operators unless otherwise indicated. However, including AND’ operators in brackets will tell the database that the combination of these keywords is of less importance than the words outside of the brackets.
Researchers can narrow down results further by using site-specific Boolean searches. Here, the word ‘site:’ acts as the primary operator, ensuring that only results gathered from a specific site are returned. Employers can combine the ‘site:’ operator with AND to define the site and content from that site that they wish to find.
2. Exclude Certain Queries
Similarly, file types can be excluded through Boolean searches. The operator ‘filetype:’ followed by the specified file format will tell the database that only results in a DOC, PDF, or JPF among others, are desired. File-specific searches can help employers identify and locate downloadable resumes and headshots as well as ensuring that all results produced are accessible to the researcher.
To optimize searches, employers should experiment with a combination of operators and keywords, refining their search in accordance with the results produced and the results they wish to have returned. Phrases or common results that are irrelevant or unhelpful can be eliminated through the NOT operator. Employers may also wish to use site-specific and file-specific operators alongside common Boolean search operators to increase the accuracy and utility of their results.
Engage Boolean Search in your Recruiting
Boolean searches, when used effectively, can be a very beneficial tool for researchers and employers alike. Researchers can ensure that only relevant and desirable results are produced by narrowing down or broadening their search results using Boolean operators. In order to maintain company productivity levels, all job positions must be filled quickly and efficiently. Boolean searches afford companies the advantage of speeding up their recruitment process by screening out candidates with less desirable skill sets or qualifications.
As a result, companies can ensure that only candidates who meet the criteria specified in their job description are considered for employment. Moreover, employers can use the Boolean search to rule out candidates who are affiliated with other companies. As a conflict of interests could hinder an employee’s ability to proficiently and comfortably perform their job, it is crucial that employers hire only candidates whose judgment or abilities are unaffected by other commitments.
By narrowing down candidate lists efficiently, companies can streamline their recruitment process, ensuring that the time taken to select the right recruit is spent productively.
