# All Field Instances Match a Specified String or Number

You can use the following field specifiers (case sensitive) to return documents with multiple instances of the same fields and all field instances contain a specified string or number.

## MATCHCOVER

The `MATCHCOVER` field specifier (case sensitive) allows you to find documents in which the values in all instances of a specified field have matches in the set of values provided in the specifier. In other words, the specifier must cover all instances of the field. A search that uses `MATCHCOVER` is slower than one that uses `MATCH`.

NOTE: You can optimize the field specifier speed by restricting the field to the `MatchType` and `CountType` property types. You must specify both property types.

    FieldText=MATCHCOVER{yourStrings}:yourField

where:

`yourStrings` | is one or more strings. A document returns only if the value in each of its instances of `yourField` matches one of the strings in `yourStrings`. Separate the strings with commas (there must be no space before or after a comma). FieldText queries which include commas and braces within the query have specific percent-encoding requirements. For information about percent-encoding, see FieldText.
`yourField` | is 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 is found in `yourStrings`. it does not contain the field at all.

Example:

    FieldText=MATCHCOVER{Confidential,Secret,TopSecret,FBI}:SECURITYLEVEL

For a document to return as a result, its `SECURITYLEVEL` fields must not contain any values that are not in the specified list. For example, if a document includes a `SECURITYLEVEL` field with the value MI5, it does not return. (If a document has no `SECURITYLEVEL` field at all, it returns.)

## EQUALCOVER

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.

    FieldText=EQUALCOVER{yourValues}:yourField

where:

`yourValues` | is 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). FieldText queries which include commas and braces within the query have specific percent-encoding requirements. For information about percent-encoding, see FieldText.
`yourField` | is 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.

Example:

    FieldText=EQUALCOVER{9,10,11,12}:GRADELEVEL

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, it returns.)
