I have a few questions about the search index:
o The Search page (
) says, "Information about a page's content is added and updated when a page is viewed by a user. Each page includes an invisible image which calls the index update process if needed." How is it determined if an index update is needed?
o What's the server load for updating the index?
o Some shared hosting companies have policies on running cron jobs, and techniques like this may be interpreted as attempting to circumvent their policies. Is there a way to do index updates via cron rather than via a hidden image?
P.S. I'll add the answers into the DokuWiki documentation wiki...
