  For faster and better search functionalities EMC has developed a Full Text Index Server which is installed separately with the Content management software to provide an index based search capability. In version 5.2.5 SPx the full text search engine was using Verity which has been now changed to FAST (Fast Search & Transfer) in 5.3 SPx onwards and xPlore replaced further. In Verity we have to explicitly define the attributes to be indexed, in the content server configuration, whereas one of the salient features of FAST is that by default, all the attributes are indexed along with the content of the document.   Since, FAST is no longer tightly coupled with the installation of the content server; one has the option of not installing Index  Server. If the Full Text Index server is not installed, simple search will perform a case sensitive database search against  object_name ,  title  and  subject  attributes of dm_sysobject and its subtypes.

  This Post explains how the concept of relationships and virtual documents can be used to relate objects in Documentum using Documentum Foundation Classes (DFC). Definitions: Relationship : A relationship implies a connection between two objects. When an object is related to another object then we can define which object is the parent object or the child object or if they are equal. Relationships are system-defined as well as user-defined. In the BOK, we confine our self to user-defined relationships. Virtual Document : In Documentum, a document which holds other documents i.e. a document which acts as a container is called as a virtual document. A virtual document can contain other virtual documents. The document which acts as a container is called the parent document while the documents which are contained in parent document are called as child documents. Overview on relationship : Two built-in object types  dm_relation  and  dm_relation_type  are to be used ...
