Abstract

A computer implemented method and system include executing a search against both a client cache associated with a client and data sources remotely coupled to the client over a network connection. Results from the search against the client cache are rendered on a client UI. The client cache and the client UI are updated with the results from the search against the data sources.

First claim

We claim:

1. A computer implemented method comprising:
executing, by a computing device, a search against a client cache included in the computing device;
rendering, by the computing device, results from the search against the client cache on a client user interface (UI) included in the computing device;
providing, by the computing device, a request to an application server that is remote from the computing device and the application server: (i) executes the search against data sources remotely coupled to the computing device over a network connection (ii) stores, in a server cache, results from the search against the data sources remotely coupled to the computing device and (iii) returns the results from the search against the data sources remotely coupled to the computing device;
receiving, by the computing device, the returned results from the search against the data sources remotely coupled to the computing device;
updating, by the computing device, the client cache and the client UI with the returned results from the search against the data sources remotely coupled to the computing device;
receiving, by the computing device, (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis, wherein the refresh of the server cache comprises re-executing a search against the data sources remotely coupled to the computing device over the network connection and refreshing the server cache based on the re-executed search against the data sources remotely coupled to the computing device over the network connection;
after receiving, by the application server, the request by a user for a refresh of the server cache on a periodic basis, refreshing, by the application server, the server cache with information from the data sources at an interval specified by the user by re-executing a search against the data sources remotely coupled to the computing device over the network connection and refreshing the server cache based on the re-executed search against the data sources remotely coupled to the computing device over the network connection; and
providing, to the application server, (i) the request by a user for a refresh of the server cache and/or (ii) the request by a user for a refresh of the server cache on a periodic basis.

2. The method of claim 1 further comprising initializing the client cache with records.

3. The method of claim 1 further comprising:
providing the network connection between the computing device and the application server;
closing the network connection at a predetermined time in the absence of network activity; and
reestablishing the network connection upon indication of a user.

4. The method of claim 1 wherein the refresh of the server cache comprises refreshing the server cache in entirety based on the re-executed search against the data sources remotely coupled to the computing device over the network connection.

5. The method of claim 1 further comprising:
providing the network connection between the computing device and the application server;
closing the network connection at a predetermined time in the absence of network activity; and
reestablishing the network connection upon indication of a user.

6. The method of claim 1 wherein the receiving, by the computing device, (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis comprises:
receiving, by the computing device, a request by a user for a refresh of the server cache on a periodic basis;
wherein the providing, to the application server, (i) the request by a user for a refresh of the server cache and/or (ii) the request by a user for a refresh of the server cache on a periodic basis comprises:
providing, to the application server, the request by a user for a refresh of the server cache on a periodic basis; and
the method further comprising:
after receiving, by the application server, the request by a user for a refresh of the server cache on a periodic basis, refreshing, by the application server, the server cache with information from the data sources when a duration since a prior refresh exceeds a predetermined maximum time by re-executing a search against the data sources remotely coupled to the computing device over the network connection and refreshing the server cache based on the re-executed search against the data sources remotely coupled to the computing device over the network connection.

7. The method of claim 1 further comprising refreshing, by the application server, the server cache with information from the data sources upon notification from the data sources.

8. The method of claim 1 further comprising providing an index of data in the data sources.

9. The method of claim 1 wherein the duration between the executing, by the computing device, and the rendering, by the computing device, is less than approximately a second.

10. The method of claim 1 wherein the network connection is a wireless network connection.

11. The method of claim 1 wherein the receiving, by the computing device, (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis comprises:
receiving, by the computing device, a request by a user for a refresh of the server cache on a periodic basis; and
wherein the providing, to the application server, (i) the request by a user for a refresh of the server cache and/or (ii) the request by a user for a refresh of the server cache on a periodic basis comprises:
providing, to the application server, the request by a user for a refresh of the server cache on a periodic basis.

12. The method of claim 1 wherein the receiving (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis, wherein the refresh of the server cache comprises re-executing a search against the data sources remotely coupled to the client over the network connection and refreshing the server cache based on the re-executed search against the data sources remotely coupled to the client over the network connection comprises:
receiving (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis, wherein the refresh of the server cache comprises re-executing a search: (a) for records that match a text string received from a user via a user interface (b) against the data sources remotely coupled to the client over the network connection, and refreshing the server cache based on the re-executed search (1) for records that match the text string received from the user via the user interface (2) against the data sources remotely coupled to the client over the network connection.

13. The method of claim 1 wherein the receiving (i) a request by a user for a refresh of the server cache and/or (ii) a request by a user for a refresh of the server cache on a periodic basis, wherein the refresh of the server cache comprises re-executing a search against the data sources remotely coupled to the client over the network connection and refreshing the server cache based on the re-executed search against the data sources remotely coupled to the client over the network connection comprises:
receiving (i) a request by a user for a refresh of the server cache, wherein the refresh of the server cache comprises re-executing a search: (a) for records that match a text string received from a user via a user interface (b) against the data sources remotely coupled to the
