# caseExactJsonIdMatch

This matching rule is used for attributes whose values are JSON objects. With this rule, only the `"_id"` fields matter for matching. In other words, two JSON objects are considered equal if their `"_id"` values match, regardless of other values.

Respect case when finding matches. For example, `BJensen` and \`bjensen\`*do not* match.
