The Spider
The Spider, Selection on Keywords, Limiters on Words, Limiters on Sites, Displaying Sites.
  The spider has the central role in supplying the raw information in answer to the user's question. In the uttermost top-left corner of the interface, the status of the spider and the connection to it is show. The figure above shows the functional design of the spider interface on the left hand side and on the right it shows the corresponding implementation.

Connections to the spider are short lived because the spider has to maintain a process for the query. For possibly many thousands of requests in parallel, this is not acceptable.

Examples on useful facts which can be displayed here are

  • the size of the databases of the spider;
  • the connection-time and -status to the spider;
  • the amount of data still to be produced by the spider to have a fully updated screen; and
  • the load on the spider.
At this point `we start with everything'.
