Query Basics

Queries support two types of terms:

Single Term	A single word	test, hello
Phrase	A group of words surrounded by double quotes	"hello flashduty"

Boolean Operators

Operator	Description	Example
AND	Intersection: both terms must be in the selected view (default operator)	error AND timeout
OR	Union: either term is contained in the selected view, must be wrapped in ()	(error OR warning)
-	Exclusion: the following term is not in the view	error -timeout

Full-Text Search

Query	Description
hello	Fields that exactly match hello
hello*	Fields that start with hello
*hello	Fields that end with hello
*hello*	Fields that contain hello
"hello world"	Fields that exactly match "hello world"

When searching for field values containing special characters, you need to escape them with backslash \ or use double quotes.

The following characters are considered special: :, ", *, -, >, <, ,, (, ), [, ], \ and space
