Abstract: Indexing and searching features are provided including associated system, methods, and other implementations. A computing system of an embodiment is configured to reuse or repurpose physical index fields for different tenants as part of providing efficient and scalable indexing and searching services. A method of one embodiment operates to provide an indexed data structure that includes a number of reusable index fields that are shared and used to index information associated with a plurality of tenants. Other embodiments are included.

Abstract: Embodiments provide indexing and searching features including the use of a configurable schema as part of providing partial update support of one or more aspects of an electronic document or documents, but are not so limited. In an embodiment, a system is configured to provide search services including partial update functionality based in part on use of a configurable schema to manage partial document updates and/or query processing operations. A method of one embodiment operates to use a configurable schema to define a number of merge sets that group various document attributes based in part on data source, update, and/or usage parameters to provide an efficient partial update mechanism. Other embodiments are included.

Abstract: In a method for information access, search, and retrieval over a data communication system generally, wherein a query is applied to a set of documents, a result set of the matching documents are identified. The method comprises amending the query according to the access entitlements of the current user to the original documents in source systems, in such a way that only documents the user is allowed to access directly from various source systems appear in the result set, even when the source documents reside in systems of different security domains that potentially are dependent on each other.
