Xapian does not index special characters as search terms by
default. Hence it will not be possible to search for them. It
seems to be possible with some customization though. See
xapian-discuss for some clarification

    http://grokbase.com/t/xapian/xapian-discuss/0842sy96ck/using-special-characters-in-query-terms#20080402c9j4zsq14dnn99j0wfyn96kf24

I have forwarded a patch upstream to clarify the error presented
to the user.

Thanks for your attention to detail!
