Abstract: The invention in some embodiments features a contextual content delivery system (CCDS) for enhancing conventional web content with pop-up bubbles that display information when a cursor hovers over a word, link, or icon. The CCDS is configured to identify words or links in a document, determine their context, select the appropriate bubble from a plural of bubble types for each of the words or links, select content for each bubble based, in part, on the context in which the words and hyperlinks are used. The context can be determined from various sources including the resource in which the word or link appears and the target resource to which the link points. Thereafter, the CCDS enhances the words or links so that bubbles are automatically invoked in response to the appropriate trigger.

Abstract: A search engine for dynamically generating search results for the user is disclosed. In one embodiment, the user submits a first search query for searching a primary database, such as the content obtained from the World Wide Web, and the search engine obtains primary search listings based upon the search query, which search listings are distinguished from banner advertisements. The system then performs a further search of one or more secondary databases. The secondary search is initiated by the user or automatically by the system, based upon one or more search parameters. The secondary databases may include internal databases maintained by a provider of goods or services, databases that are updated in real time, or databases that include data obtained from a variety of different sources. Examples of secondary databases include inventory databases, product information databases, scheduling databases, market-related databases, location databases or any other database.
