Computerized system and method for search query auto-completion

A non-transitory computer-readable storage medium tangibly encoded with computer-executable instructions, such that when a computing device executes the instructions, a method is performed comprising:

• receiving, at the computing device over a network, user input information from a user device, said user input information comprising a character string of at least one character and a device identifier (ID);
• determining, via the computing device, a set of text suggestions that begin with the character string from a lexicon database;
• identifying, via the computing device, a set of applications installed on the user device based on the device ID;
• determining, via the computing device, a status each of the installed applications on the user device, said status comprising information indicating when a respective application has last been opened, a time a respective application has been installed, and whether a respective application is currently opened;
• compiling, via the computing device, a query auto-complete (QAC) suggestion listing based on the set of text suggestions and the installed applications, and the installed application's determined status, said QAC suggestion listing comprising text suggestions associated with the installed applications being ranked higher than other text suggestions that are not associated with the installed applications;
• and
• communicating, via the computing device over the network, the QAC suggestion listing for display on the user device.

A computing device comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium for tangibly storing thereon program logic for execution by the processor, the program logic comprising:
• logic executed by the processor for receiving, at the computing device over a network, user input information from a user device, said user input information comprising a character string of at least one character and a device identifier (ID);
• logic executed by the processor for determining, via the computing device, a set of text suggestions that begin with the character string from a lexicon database;
• logic executed by the processor for identifying, via the computing device, a set of applications installed on the user device based on the device ID;
• logic executed by the processor for determining, via the computing device, a status each of the installed applications on the user device, said status comprising information indicating when a respective application has last been opened, a time a respective application has been installed, and whether a respective application is currently opened;
• logic executed by the processor for compiling, via the computing device, a query auto-complete (QAC) suggestion listing based on the set of text suggestions and the installed applications, and the installed application's determined status, said QAC suggestion listing comprising text suggestions associated with the installed applications being ranked higher than other text suggestions that are not associated with the installed applications;
• and
• logic executed by the processor for communicating, via the computing device over the network, the QAC suggestion listing for display on the user device.
