Client side system and method for search backed calendar user interface

A system configured to produce a multi-user calendar interface, the system comprising:

• one or more processors configured by machine-readable instructions to:
• store, by a server system, an information structure that associates attribute information with code objects, the code objects corresponding to tasks previously assigned to individual users, wherein the code objects are configured to facilitate generation of visual content items corresponding to the tasks;
• receive, at a user device associated with a first user, a search query input through a search interface, the search query identifying a second user and a third user;
• match, at the server system, the second user and the third user identified in the search query with the attribute information stored by the server system to identify multiple ones of the code objects for the multiple ones of the tasks previously assigned to the second user and the third user;
• in response to matching, transmit, by the server system to the user device, information that identifies the multiple ones of the code objects for the multiple ones of the tasks previously assigned to the second user and the third user;
• and
• in response to transmitting, effectuate generation of a set of the visual content items for the multiple ones of the tasks previously assigned to the second user and the third user within a calendar date pane display grid of a multi-user calendar interface displayed via the user device, the set of the visual content items being generated in accordance with the multiple ones of the code objects for the multiple ones of the tasks previously assigned to the second user and the third user such that a first subset of the set of the visual content items associated with the second user include indicia identifying the second user, and a second subset of the set of the visual content items associated with the third user include indicia identifying the third user, the calendar date pane display grid comprising a two-dimensional display grid of date panes that individually correspond to individual days of a month.
