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 remedial measure further comprises at least one of transmitting optimization data to a merchant, associating the search term with the item, modifying product data associated with the item, writing the search term to a log as a potential missing search term, or modifying a search algorithm.
