When searching for multiple words for "Title:", the
results display just fine.  The previous & next links,
however, return only empty results.

The previous & next links have this at the end of the URL:

...&@filter=title&title=word1,word2

If the URLs are changed to 

...&@filter=title&title=word1&title=word2

they work just fine.

I created a patch for this, although I don't know if
it's the best solution.  I hope that this patch will be
included in the next release, or the underlying cause
can be found.  I suspect that a better solution would
be to make the filtering support 'word1,word2'.

Thanks!
