Comment (by duck_):

 Replying to [comment:6 tomauger]:
 > If the issue is extra whitespace creeping into the output of the Search
 results (which TBH doesn't make sense to me, since HTML chomps whitespace
 ordinarily), then why not run a quick RegExp that trims that whitespace
 before outputting? (eg: s/^\s*// to trim leading whitespace). Just putting
 an idea out there.

 It seems that in this case the problem is that XML is being returned and
 this is indicated by a text/xml Content-Type header. Unfortunately the
 whitespace before the opening xml declaration means that jQuery throws an
 error when trying to parse it. This means that the error AJAX callback is
 used which tries to use the returned responseText which is the returned
 XML, but strips all the XML tags leaving a CDATA tag which is displayed by
 the browser but invisible.

 We could check if textStatus == 'parseerror' and display a message in the
 error callback.
