Operators are always written in uppercase English letters (AND, OR, NOT).<\/p>\n<h4>1. AND Operator (Logical &#8220;AND&#8221;)<\/h4>\n<p>Used to combine several mandatory conditions. The search engine will find only those profiles that contain all the specified words simultaneously.<\/p>\n<p><strong>Example<\/strong>: Java AND Spring AND Angular<br \/>\n<strong>Result<\/strong>: Only candidates whose resumes contain all three technologies.<\/p>\n<h4>2. OR Operator (Logical &#8220;OR&#8221;)<\/h4>\n<p>Expands the search by using synonyms, alternative job titles, or related technologies. The search engine will find profiles where at least one of the specified words appears.<\/p>\n<p><strong>Example<\/strong>: Recruiter OR &#8220;Talent Acquisition&#8221; OR Sourcer<br \/>\n<strong>Result<\/strong>: Candidates who have at least one of these three roles listed.<\/p>\n<h4>3. NOT Operator (Logical &#8220;NOT&#8221;)<\/h4>\n<p>Excludes words you do not need from the search results (for example, related roles or higher qualification levels).<\/p>\n<p><strong>Example<\/strong>: Developer NOT Lead NOT Director<br \/>\n<strong>Result<\/strong>: Developers, but without team leads and technical directors.<\/p>\n<h3>Additional Symbols and Syntax<\/h3>\n<p>In addition to the three basic operators, Boolean Search uses additional symbols for precise query formulation:<\/p>\n<ul>\n<li><strong>Quotation marks &#8220;&#8221; (Exact phrase)<\/strong>: search for a phrase exactly in the order in which it is written. <em>Example<\/em>: &#8220;Project Manager&#8221; (without quotation marks, the search engine will search for the words Project and Manager separately).<\/li>\n<li><strong>Parentheses () (Grouping):<\/strong> allow you to combine different operators in one query according to mathematical rules. <em>Example:<\/em> (Python OR Django) AND (Junior OR Middle)<\/li>\n<li><strong>Asterisk * (Truncation \/ Wildcard):<\/strong> searches for all possible word endings (works in most internal databases and some search engines). <em>Example<\/em>: recruit* will find recruiter, recruiting, recruitment.<\/li>\n<\/ul>\n<h3>Ready-to-Use Boolean Search Queries for Recruiters<\/h3>\n<p><strong>Example 1: Searching for a Middle Fullstack Developer (Node.js + React)<\/strong><\/p>\n<p>(&#8220;Fullstack Developer&#8221; OR &#8220;Full Stack Developer&#8221;) AND &#8220;Node.js&#8221; AND React NOT Junior<\/p>\n<p><strong>Example 2: Searching for a B2B Sales Manager in Kyiv<\/strong><\/p>\n<p>(&#8220;Sales Manager&#8221; OR &#8220;Account Executive&#8221; OR &#8220;Business Development&#8221;) AND B2B AND Kyiv<\/p>\n<p><strong>Example 3: Searching for an IT Recruiter with Sourcing Experience<\/strong><\/p>\n<p>(Recruiter OR &#8220;Talent Acquisition&#8221;) AND IT AND Sourcing<\/p>\n<h3>4 Common Boolean Search Mistakes Made by Beginners<\/h3>\n<ul>\n<li><strong>Operator capitalization<\/strong>: if you write and or or in lowercase, the search system will interpret them as ordinary words rather than logical commands.<\/li>\n<li><strong>Forgotten quotation marks<\/strong>: without quotation marks, the query HR Business Partner will be treated by the system as HR AND Business AND Partner, which will produce a lot of &#8220;noise&#8221;.<\/li>\n<li><strong>Missing parentheses<\/strong>: the query Java OR C++ AND Developer will be executed incorrectly. You need to group the terms: (Java OR C++) AND Developer.<\/li>\n<li><strong>Overly complex first query<\/strong>: start with a short query and gradually add AND\/NOT operators if the results are too broad.<\/li>\n<\/ul>\n<h3>Save Candidates from Boolean Search Directly to PersiaHR<\/h3>\n<p>Found an ideal profile on LinkedIn or a file-based resource using a Boolean query?
