1. A method comprising: establishing, from a merchant site, communication between the merchant site and a generalized search entity via a communication interface, wherein the generalized search entity: presents an input field on user interface of the generalized search entity, wherein the generalized search entity processes data using a generalized search engine that indexes and searches both merchant sites and non-merchant sites; receives a text-based query in the input field; correlates the text-based query against a product database of products for sale from merchants to yield a correlation; determines, via a processor and based at least in part on the correlation, that the text-based query is associated with one of a search intent and a purchase intent to yield a determination; and when the determination indicates the search intent: presents a search result comprising a non-merchant site; receives a search interaction associated with the non-merchant site; and transitions, based on the search interaction, to the non-merchant site; and when the determination indicates the purchase intent: presents a purchase-related search result comprising a buy option associated with the text-based query, wherein the purchase-related search result is configured such that when a user interacts with the purchase-related search result and confirms a purchase via interacting with the buy option, the generalized search entity initiates processing of the purchase of an item; and receives an interaction from the user associated with the purchase-related search result.

The method of claim 1 , wherein the generalized search entity further: receives, from the user, an interaction with the buy option; and manages the purchase of the item based on payment information stored at the generalized search entity, wherein delivery of the item is handled via the merchant site separate from the generalized search entity.
