Does a special character lika a "-" prohibitor operator require no-space after

Typically on the web, e.g. Google and others, the "-" operator works as a
boolean prohibitor only when not followed by a space. Otherwise it is treated as just a
dash query term.
But in our Lucene implementation the the "-" seem to be acting as a prohibitor even if
there is space after it. For example. in a query: Sales + service , the 'service' term is
excluded by Lucene. (Same for the "+" operator.)
Is this space-treatment a bug or a standard Lucene query parser behavior?
I think this is expected, and changing it would be more confusing. Consider:
If "-" is expected to find a dash, surely "-x" should find a dash
followed by an x?
If you want literals, put quotes around your terms...
"Sales + service"
