Log message (14 lines):
include/xapian/queryparser.h,queryparser/queryparser.cc,
queryparser/queryparser.lemony,queryparser/queryparser_internal.h,
tests/queryparsertest.cc: Since calling QueryParser::add_prefix()
or QueryParser::add_boolean_prefix() a second time with the same
field name was ignored before (rather than overriding as we had
thought) it seems reasonable to change this behaviour.  This
also avoids the need to deprecate these methods which will force all
users to update their code.  Change the semantics of default_prefix
- it's more useful if this overrides any default prefixes set with
add_prefix(), since this allows the same QueryParser object to
parse both a "general" search input which searches several fields
and also a "title" search input.  Trying to set the same field
as probabilistic and boolean now throws InvalidOperationError
rather than UnimplementedError.
