A fix is in progress for searching with an hyphen however implicit
wildcard when searching for a package name with a prefix e.g. name
:ubuntu-res is not possible with the current version of xapian:

Extract from the discussion on #xapian:
"It needs two new options: firstly, to make it handle wildcards (and implicit 
wildcards from FLAG_PARTIAL) for boolean fields and secondly to make it handle 
wildcards and implicit wildcards at the end of hypenated phrases."

A workaround (but very bad practice) is to replace '-' by '* ' when the prefix 
'name:' and replace '-' by ' ' when no prefix is used. 
With this a query such as 'name:ubuntu-res' will be parsed as XPubuntu* AND 
res* (with wildcard expansion) 
but a query such as 'name:(ubuntu-res*)' won't return anything

** Changed in: synaptic (Ubuntu)
