Unless you automate it (basically a cron job setting, except that if you have to reindex thousands of pages you better use different and smaller sets of pages reindexed at different times), indexing your site from a browser page (which xav can do) is slow, boring and time consuming. More about this can be found on the help pages on the Xav web site.
Yes, full string means the entire search phrase used, while of course single words apply to all the words used in all the search strings entered.
Whenever you add content to your site you have to reindex it, if you want that content to show up in your results pages. It is not a big deal if you atomatically reindex your site or if your site doesn't change every day, otherwise you will have to manually do the reindexing (doing that from the browser with freefind is a single click with no need to wait after that, while with Xav you'll have to wait for the full crawl to be finished...).
