Each predicate from is represented as a bitwise predicate pattern to generate a set of bitwise predicate patterns. A set of valid bitwise patterns from the set of bitwise predicate patterns is identified using the first query. The set of valid bitwise patterns is parsed using logical operators to generate a logical bitwise expression. The logical bitwise expression is factored and the factored logical bitwise expression is mapped to corresponding predicates to generate a logical predicate expression. A second query is generated, which includes modifying the first query using the logical predicate expression and at least one logical operator. A subset of data is retrieved from the data repository using the second query."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Query optimization","description":"A first query is received including a logical expression as a set of predicates in Disjunctive Normal Form.
