Match Semantics
Content matchers interpret match strings using these simple rules.
- If the match string specifies a field with boolean token
true, that field must be present in the message in order to match. - If the match string specifies a field with boolean token
false, that field must be absent from the message in order to match. - If the match string specifies a field with either a string or long integer value, that field must be present in the message with that value.
- When comparing a field name or a value, all comparisons must be exact. Matching does not support wildcards nor regular expressions.
