11. A method for facilitating data searching over a network, the method comprising: receiving a search request from a user device via the network, wherein the search request includes information related to the user device; processing the search request by identifying a context chain related to the user device based on the information and by using the context chain to obtain a search result in response to the search request, wherein the context chain includes a plurality of contexts that are publishing spaces in which interpretation of the search request takes place by using content published to the publishing spaces by publishers of different viewpoints, wherein the processing the search request includes: examining contexts in the context chain in a last-in-first-out order in which the most recently added contexts to the context chain are examined before earlier added contexts, and wherein at least one context of the context chain is independently searchable with respect to other contexts of the context chain; and providing the search result to the user device.
