Abstract: Systems and methods for implementing a query-based hold on electronic items hosted by a communication device and/or system. Electronic items from a plurality of user-specific folders are purged and copied to a discovery hold folder. The purged items, along with all existing items, contained within the discovery hold folder are evaluated against the query-based hold criteria. Items that fail to meet the query-based hold criteria are permanently deleted from the discovery hold folder. Items that meet the query-based hold criteria are maintained within discovery hold folder.

Abstract: A web Application Programming Interface (API) server receives a statistics request from a client. The statistics request is a request to invoke an item counting method defined in an API provided by the web API server. The statistics request specifies a keyword string and multiple target data repositories. As a response to the statistics request, the web API server sends a statistics response to the client. The statistics response specifies an item count that indicates how many relevant items are in the target data repositories. Each of the relevant items is associated with at least one keyword in the keyword string.
