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.
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.
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 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:
|
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.)
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.
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 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:
|
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.)
