WebTrader Application: DeepSearch
DeepSearch is an application of the WebTrader. In this case, the advertisements of interest are service ads for search engines. Many web search engines only index top-level pages leaving the other half of the web unindexed except by these local search engines. So DeepSearch recursively (via federation) locates these local search engines and spawns deeper searches of these.
You start out with the main search page (shown on the right). You select your favorite initial search engines (any or all - e.g., this part just shows metasearching in parallel) and enter a search term like you do for any search engine and hit return. Then the side window pops up with the search results, and as you click on the links, the corresponding pages come up in the main browser window. Local search engines found during searching show up among the links - you can expand them to get the results of their searches, just like you can expand a directory in the Windows File Explorer.
