Useful research - dependence of query processing time on result set size and visibility density for different classes of user. Scaled up to collections of tens of thousands of documents, our results suggest that query times will be unacceptable if exact counts of matching documents are required and also for users who can view only a small proportion of documents. We show that the time to conduct access checks is dramatically increased if requests must be sent off-server, even on a local network, and discuss methods for reducing the cost of security checks. We conclude that enterprises can effectively reduce DLS overheads by organizing documents in such a way that most access checking can be at collection rather than document level, by forgoing accurate match counts, by using caching, batching or hierarchical methods to cut costs of DLS checking and, if applicable, by using a single portal both to access and search documents.
A synthesis of many cases where Sharepoint has been implemented so haphazardly that the results complex structures and frustrating user experiences. Jeff Carr identifies key components for success with SharePoint: purpose, governance, people & objectives, requirements, IA, technology, and maintenance.
RAMP site search indexes text, images, audio, and video with its own transcript-creator and MetaPlayer interface. It provides faceted search results, as well as federated and "blended" search, and has contextual content recommendations and interface widgets, search suggestions, spell correction, and keyword merchandising The search is designed to work with the company's Publishing, Workflow, Video and Advertising modules, but may not depend on them. It's SaaS and the pricing model is mysterious but probably fairly high.
