12. A system, comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the system to: analyze an image including a representation of an object using a first classifier to determine a product category associated with the object; analyze the image using a second classifier algorithm to determine a term representing a visual characteristic of the image; analyzing the image using the second classifier algorithm with the term to determine a sequence of words describing visual characteristics associated with the object; determine that the sequence of words satisfies a search condition; generate, in response to the sequence of words satisfying the search condition, a search string query that includes a subset of the sequence of words and search string refinement terms associated with the product category and the sequence of words; determine a set of search results based at least in part on the search string query that includes an item from a catalog of items; and display the set of search results and the search string refinement terms on a computing device, the search string refinement terms being selectable, the search string query being configured to be editable in response to a selection of one of the search string refinement terms.
