Computer-readable media and methods to provide a toolbar application are described. The toolbar application receives indicators for determining when a context-specific search is executed. The toolbar application monitors uniform resource locator (URL) addresses to which a browser navigates for the inclusion of an indicator. Upon identifying an indicator in a URL the toolbar application presents filters that are associated with the indicator in a toolbar user interface. A user's selection of one or more of the filters is received at the toolbar user interface and the corresponding filters are applied to the context-specific search results by modifying the identified URL with a modifier associated with a selected filter and causing the browser or search engine to re-execute the search query with the selected filters applied. The filtered search results are presented to the user. The toolbar user interface is modified to indicate the application of the selected filters.
