Abstract
Search and filtering of documents with different metadata schemata is enabled using a single index that supports a single schema through decorated namespaces. Each metadata schema submitted to a system is assigned a unique identifier and property names associated with the schema are prefixed with the unique identifier. A single-valued, decorated property is used to indicate whether a submitted document is part of a registered schema in the system. The single-valued properties are converted to a search index table that enables resource-optimized searching and filtering of documents eliminating documents of other schemata by simply checking the association property.
