A method, system, and computer program device implements a search in, for example, a healthcare provider medical information portal. For example, instead of having to type or key a search item into an interface, the search may be conducted, automatically, for data records relevant to the item by executing a search query event. More particularly, the search query event identifies the item, which may be displayed in a user interface, to be searched. In addition to identifying the item, the search query event also initiates the search. In one example, the search query event includes positioning a cursor over a phrase, term or other item displayed on a webpage and clicking a mouse button. The present invention requires fewer interactions to execute a search. The search technique may be implemented with any type of portal.
