7.1.4 exact: Exact Matching

matcher=exact values*='<matched-value>'
values*:
  • matched-value: Value for exact match

The exact matcher compares arbitrary key values for exact equality. Rows are considered to match only if the values in their matched-value columns are exactly the same. These values can be strings, numbers, or anything else. A blank value never matches, not even with another blank one. Since the params parameter holds no values, it does not have to be specified.
