You use multiple filters, the last one overrides previous ones. E.g. to accept
only pages with url containing X unless it also contains a Y you use:
-* +*X* -*Y*
i.e. reject all, accept X, reject Y

If you also want images, css, js formatting etc you also have to allow them
(+*.css +*.js) or if you want everything use the near flag (get non-html files
related)
