Bug 19873: Ability to search on 0 value

Test plan:
  - create a st-numeric index in zebra conf related to
    a numeric field
    i.e:
    yourindex 1=yourindex 4=109
  - fill a field with 0 in a biblio,
  - reindex your biblios,
  - search yourindex=0,
  - should not work,
  - apply this patch,
  - test again,
  - should work
