Abstract: Systems and methods for dynamically disaggregating product variants in online search are disclosed. In some embodiments, a disclosed method includes: obtaining, from a computing device, a search request identifying a query and seeking N items to be displayed on a search result page of a website to a user, wherein N is a positive integer; determining, dynamically based on the query and N, an integer M; searching, based on the query, a database to identify M items associated with the website, wherein the M items comprise at least one subset of items that include at least one variant of a product; generating, from the M items, a ranked list of N items; and transmitting, to the computing device, the ranked list of N items in response to the search request.

Abstract: Systems and methods for generating an interface including variant item elements are disclosed. A request for an interface including a search query is received from a first device and a set of candidate items is generated by a first level search model based on the search query. The first level search model generates a baseline value for each item variant in an item catalog including a weighted combination of a relevance label value and an engagement label value. The set of candidate items is selected based on the baseline value. A set of search results is generated by a second level search model based on the set of candidate items. An interface including interface elements representative of one or more item variants in the set of search results is generated and transmitted to the first device.
