![]() Otherwise, the search will misinterpret where the field name ends. If a field name contains a single quotation mark ( ' ), that single quotation mark must be escaped. Because the search can't interpret the rest of the WHERE clause, the search returns a syntax error.įield names that contain anything other than letters, numbers, or the underscore ( _ ) character must be enclosed in single quotation marks ( ' ). If you don't escape the quotation marks around the username "vpatel" the search interprets the string value as "The user ". WHERE _raw="The user \"vpatel\" isn't authenticated."

To escape a backslash character ( \ ), use the sequence \\ to search for a backslash. To escape a double quotation mark ( " ), use the sequence \" to search for a literal double quotation mark. Also referred to as the Horizontal Tab escape sequence. Also referred to as the Carriage Return escape sequence. Also referred to as the Formfeed Page Break escape sequence. The following table shows the characters and escape sequences that must be escaped in your searches: When you apply a backslash to an escape sequence that is inside quotation marks, the escape sequence is expanded inside the quotation marks.Ĭharacters and escape sequences that must be escaped To ignore an escape sequence in your search, prepend a backslash character to the escape sequence. For example, the escape sequence \n represents a new line character. For example: more information about raw string literals, seeĪn escape sequence is a set of characters used in string literals that have a special meaning, such as a new line, a new page, or a tab. However, instead of escaping the backslash character, you can designate the path C:\windows as a raw string and precede the string with the at symbol ( ).

Raw string literals must be preceded by the at symbol ( ) and enclosed in double quotation marks. WHERE `user "ladron" from 192.0.2.0/24`įor more information, see Search literals in expressions.Ī raw string literal is an expression in which the backspace character ( \ ) is not processed. You specify the search literal in the WHERE clause of the from command: The quoted string inside the set of terms doesn't need to be escaped. You must enclose the terms in backtick characters ( ` ). ![]() Internally the search becomes user AND "ladron" AND from AND 192.0.2.0/24 With a search literal, an AND condition is implied between each of the terms. To search for these terms you can use a search literal. You want to search for the terms user "ladron" from 192.0.2.0/24 in these events.
