The various sites are indexed and the files added to your local ISYS index. Because the Spider is built upon the ISYS text indexing and retrieval engine, ISYS Spider can deal with more than just HTML pages. Any number of spiders can run at the same time and you have complete traversal frequency control. This means that ISYS Spiders can run continuously, on request, or at the various times you set. Similarly, the index update is up to the user.
Indexing can occur at the end of traversals, regular intervals or at certain times of the day.
The ISYS index remains fully functional during the spidering process, therefore not interrupting normal ISYS use. When searches are performed, the information is returned in a continuous fashion. The results page serves external information intermixed with hits from internal documents, with no distinction made between them and any special actions are performed transparently. This brokering mechanism is what makes ISYS Spider unique. When ISYS accesses documents from external domains, the brokering process serves up the text complete with hit highlighting and hit to hit navigation but the graphics attached to the page goes directly to your browser.
