Space-padded +/- has semantic impact in QueryParser
---------------------------------------------------

                 Key: LUCY-140
                 URL: https://issues.apache.org/jira/browse/LUCY-140
             Project: Lucy
          Issue Type: Bug
          Components: Search
            Reporter: Marvin Humphrey
            Assignee: Marvin Humphrey
            Priority: Minor
             Fix For: 0.1-incubating


In Lucy's QueryParser syntax, plus and minus symbols, used to require or
forbid terms/subqueries, should only apply if they are directly prepended.
Right now, a bug in QueryParser.c causes them to apply when there is
whitespace separation.

These two query strings produce identical results, but should not:

{noformat}
    a - b
    a -b
{noformat}
