Systems and methods for expanding search results

A system for expanding search results, the system comprising:

• an identification module that identifies, within results of a search, a document that is a member of a document family that includes at least one other document;
• a determination module that determines that a user has made a selection to include, within the results of the search, the document family;
• a creation module that creates a data map that includes a representation of the document identified within the results of the search at least in part by identifying a unique identifier associated with the document that corresponds to an offset within the data map and representing the document by toggling a bit at the corresponding offset on the data map;
• an expansion module that expands the data map by including, within the data map, a representation of each of the at least one other document in the document family based on the determination that the user made the selection;
• an inclusion module that uses the expanded data map to include the document family within the results of the search;
• at least one processor that executes the identification module, the determination module, the creation module, the expansion module, and the inclusion module.

A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• identify, within results of a search, a document that is a member of a document family that includes at least one other document;
• determine that a user has made a selection to include, within the results of the search, the document family;
• create a data map that includes a representation of the document identified within the results of the search at least in part by identifying a unique identifier associated with the document that corresponds to an offset within the data map and representing the document by toggling a bit at the corresponding offset on the data map;
• based on the determination that the user made the selection, expand the data map by including, within the data map, a representation of each of the at least one other document in the document family;
• use the expanded data map to include the document family within the results of the search.
