I have a website I search a lot as it has conference proceedings going back over 25 years - a goldmine of useful papers. I’m trying unsuccessfully to set up a search that is restricted to that one site. More specifically to the ‘past conferences’ page and the sub-pages that sit under it with the proceedings for each past conference.
You could either use the Google plugin and append site:domain.com/subdirectory to the search term. Or you could create a search set, add the URL of the website to the Sites tab and set following of links to e.g. on the same host or in subdirectories. In this case DEVONagent will crawl the website on its own.
