The EQUALCOVER field specifier (case sensitive) allows you to find documents in which the values in all instances of a specified field are found in the set of values provided in the specifier. In other words, the specifier must cover all instances of the field.

Note: You can optimize the field specifier speed by restricting the field to the NumericType and CountType property types. You must specify both property types.


yourValues One or more numeric values. A document returns only if the value in each of its instances of yourField equals one of the values in yourValues. Separate the numbers with commas. There must be no space before or after a comma.

The name of the field to match against. A document returns only if:

  • it contains one or more instances of the field and the value of each instance equals a value in yourValues.

  • it does not contain the field at all.



For a document to return as a result, its GRADELEVEL fields must have no values that are not in the specified list. For example, if a document includes a GRADELEVEL field with the value 8, it does not return.

(If a document has no GRADELEVEL field at all, it returns.)
