14. 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 at least: determine that a search of an electronic repository for a search term surfaces an item at a position less relevant than a predefined threshold; in response to the determination that the item is surfaced at the position less relevant than the predefined threshold, determine that a behavioral association exists between the item and the search term based in part upon behavior of at least one with respect to interactions of the at least one user with the at least one computing device; in response to the determination that the behavioral association exists, determine that the at least one search term is excluded from product data associated with the item; and in response to the determination that the at least one search term is excluded, takes at least one remedial measure comprising adding the at least one search term to the product data.

The system of claim 14 , wherein the at least one computing device is further configured to at least in response to the determination that the behavioral association exists, associate the search term with at least one attribute associated with at least one other item in the electronic repository.
