How is the Quartus Prime offline help done?

[Altera_Forum]

Hi! Just a simple question that I have not been able to find an answer for: 

 When, in Quartus Prime 17.0, you go to Help -> Help Topics, a help web site opens up in you web browser. It is served locally from, in my case, file:///c:/intelfpga_lite/17.0/quartus/common/help/webhelp/index.htm  What web server is used? How is search done? It seems to send requests to google?

It's local HTML. The server is your own computer. If you do a search within the help interface, it searches the local files. I guess if it doesn't find anything locally, it also displays Google results.

I get you can serve pages from the file system, but that will only get you pages that show information and run javascript. They could send queries to google's servers, but that doesn't account for local search.

You can open any .html file on your own machine in a browser and use it as if it's on a server. I'm not sure what the issue is here.
