Systems and methods for low cost data indexing

A system, comprising:

• a data store;
• and
• at least one computing device in communication with the data store, the at least one computing device being configured to:
• determine an importance score for each of a plurality of data objects based on one or more attributes associated with the respective data objects;
• assign each of the plurality of data objects to one of at least two tiers based on the importance score;
• store subject data associated with the plurality of data objects in the data store, wherein:
• subject data associated with data objects assigned to a first tier is stored according to first indexing parameters that include a first amount of subject data, and
• subject data associated with data objects assigned to a second tier is stored according to second indexing parameters that include a second amount of subject data different from the first amount of subject data;
• and
• in response to a change in the importance score of a particular data object, reassign the particular data object to a different tier and storing subject data associated with the particular data object according to indexing parameters corresponding to the different tier.

A non-transitory computer-readable medium embodying a program that, when executed by at least one computing device, cause the at least one computing device to:

• determine an importance score for each of a plurality of data objects based on one or more attributes associated with the respective data objects;
• assign each of the plurality of data objects to one of at least two tiers based on the importance score;
• store subject data associated with the plurality of data objects in a data store, wherein:
• subject data associated with data objects assigned to a first tier is stored according to first indexing parameters that include a first amount of subject data, and
• subject data associated with data objects assigned to a second tier is stored according to second indexing parameters that include a second amount of subject data different from the first amount of subject data;
• and
• in response to a change in the importance score of a particular data object, reassign the particular data object to a different tier and storing subject data associated with the particular data object according to indexing parameters corresponding to the different tier.
