The correct answers are reporter = Ravi AND summary ~ "\[urgent, critical\]" and reporter = Ravi AND summary ~ "urgent" AND summary ~ "critical".

reporter = Ravi AND summary ~ "urgent" AND summary ~ "critical" uses two separate text search clauses that each require a word to appear in the summary. Each summary ~ "urgent" and summary ~ "critical" clause matches the given word anywhere in the free text summary and combining them with AND ensures both terms must be present in the same issue.

reporter = Ravi AND summary ~ "\[urgent, critical\]" is correct when the summary contains that exact bracketed phrase. The backslashes escape the brackets so JQL treats the brackets and the comma as literal characters and the quoted string matches that exact sequence in the summary.

reporter = Ravi AND summary in (urgent, critical) is incorrect because the in operator does not perform free text matching on the summary field. The in operator is for fields that have a predefined set of values and it will not search for words inside a free text field.

reporter = Ravi AND summary = "urgent" AND summary = "critical" is incorrect because the equality operator requires the summary to exactly equal a single string and a single summary cannot equal two different exact strings at the same time. Use text search operators when you need to find words inside a field.

reporter = Ravi AND summary ~ ("urgent, critical") is incorrect because a single quoted string with a comma is treated as one literal phrase and will not match the two words separately or in any order. The comma inside the quotes does not mean both words are matched independently.

reporter = Ravi AND (summary ~ "urgent" OR summary ~ "critical") is incorrect because OR returns issues that contain either word but not necessarily both. Use AND when both terms must appear.
