System and method for blended presentation of locally and remotely stored electronic messages

A method performed by an electronic messaging client installed on a user device, comprising:

• receiving a query, containing one or more terms, on the user device;
• executing a first search against a first plurality of electronic messages cached in a local store of the user device using the one or more terms of the query, the local store comprising nonvolatile storage, wherein the plurality of electronic messages cached in the local store have time information that falls within a user-configurable time frame having a specified start time and end time and associated with a rolling time-based synchronization window configured to the shift forward in time after a predetermined amount of time has passed;
• displaying information about at least one electronic message identified as a result of the execution of the first search in a graphical user interface rendered on a display of the user device;
• displaying an indication of a second plurality of electronic messages available in a remote store but not in the local store, the second plurality of electronic messages being different than the first plurality of electronic messages, wherein the plurality of electronic messages available in the remote store have time information that falls outside the time frame associated with the synchronization window;
• receiving a first user interaction with the indication of the second plurality of electronic messages;
• executing a second search, using the one or more terms of the query, against the second plurality of electronic messages;
• and
• displaying information about at least one electronic message identified as a result of the execution of the second search in the graphical user interface, the information about the at least one electronic message identified as a result of the execution of the second search being temporarily buffered in a memory of the user device that is separate from the local store, wherein the one or more second electronic messages are removed from the buffer when the electronic messaging client is closed.

A system, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and storing instructions that, when executed by the at least one processor, perform a method, comprising:
• receiving a query containing one or more terms;
• executing a first search against a first plurality of electronic messages cached in a local store using the one or more terms of the query, wherein the local store comprises nonvolatile storage and wherein the plurality of electronic messages cached in the local store have time information that falls within a user-configurable time frame having a specified start time and end time and associated with a rolling time-based synchronization window, the rolling time-based synchronization window configured to shift forward in time after a predetermined amount of time has passed;
• displaying, in a graphical user interface, information about at least one electronic message identified as a result of the execution of the first search;
• displaying an indication of a second plurality of electronic messages available in a remote store but not in the local store, wherein the second plurality of electronic messages are different from the first plurality of electronic messages and have time information that falls outside the time frame specified by the synchronization window;
• receiving a first interaction with the indication of the second plurality of electronic messages;
• executing a second search, using the one or more terms of the query, against the second plurality of electronic messages;
• and
• displaying information about at least one electronic message identified as a result of the execution of the second search in the graphical user interface, wherein the information about the at least one electronic message identified as a result of the execution of the second search is temporarily buffered in a memory that is separate from the local store, wherein the one or more second electronic messages are removed from the buffer when the electronic messaging client is closed.
