The combination of a full extended boolean search with a full text pattern description language creates a very powerful advanced search engine with numerous applications. If we wanted to designate \s literally we would write \\s. Goodbye Advanced Find! The result is an extended GREP expression and this is passed to the extended GREP engine to parse and carry out the search. LinkedIn Help - Using Boolean Search on LinkedIn - Due to high support volume, it may take longer than usual to hear back from our Support Agents. In addition, implicit concatenation is intuitively defined for GREP expressions but is not defined for many Boolean expressions. The list of Search Patterns is first scanned for any similarities. In a mixed Boolean-GREP environment, the GREP Or binary operator has the same meaning as the Logical “OR” operator except that in most implementations it is higher in precedence than the logical “OR.” As is explained below, the pre-processor replaces the Logical “OR” with the GREP “Or.” To avoid confusion, the user is not allowed direct access to the GREP Or, providing only one “OR.” The Logical “AND” and related binary operators can be synthesized entirely from GREP expressions. We have added a feature to help you to conduct searches simultaneously in English and French.
