Mapping type

Determines the number of application group fields that you can map to the folder field and the type of queries that the field supports.

Single
You can map the folder field to one field in each application group that can be searched from the folder. The valid search operators for a field that uses the Single mapping type are based on the field type. If the folder field type is text search or segment, the mapping type must be single.
Range
You can map the folder field to two fields in each application group that can be searched from the folder. The valid search operator for a field that uses the Range mapping type is Equal. You can use the Range mapping type to create a transaction search field. For example, assume the reports that you want to query contain a unique, sorted value, such as an invoice number. The Range mapping type allows users to locate a specific record (transaction). Content Manager OnDemand queries the database by comparing the search value specified by the user to two database fields, one for the beginning value and one for the ending value. If the search value falls within the range of both database fields, then Content Manager OnDemand adds the document to the document list.
Operator Or
You can map the folder field to two fields in each application group that can be searched from the folder. The valid search operators for a field that uses the Operator Or mapping type depend on the field type. However, Between and Not Between are not supported. You can use the Operator Or mapping type to create an either or search field. For example, assume that the reports that you want to query can contain a major and minor account number. The Operator Or mapping type allows users to locate documents that contain one or both account numbers. Content Manager OnDemand queries the database by comparing the search value specified by the user to two database fields. If either database field contains the search value, then Content Manager OnDemand adds the document to the document list.
