This document provides instructions and examples for advanced searching in JIRA Software using the JIRA Query Language (JQL). It explains how to use wildcard, fuzzy, and proximity searches; field operators like =, >, and ~; functions like created, updated, and membersOf(); and reserving special characters with quotes or backslashes when needed in searches. The examples demonstrate complex queries using keywords like AND and OR to link clauses and search for issues based on fields, text, users, and more.
