Comment 1 for bug 1032208

I'm attaching a modified biblio.extract_metabib_field_entry that should resolve this issue. On our test server this has had a fairly significant impact on row counts and table sizes:

  author_field_entry 1786920 rows before and 494144 rows after
  series_field_entry 330018 rows before and 108101 rows after
  subject_field_entry 4506630 rows before and 971917 rows after
  title_field_entry 1032180 rows before and 528558 rows after

I'm not sure if this translates to faster searches but it "feels" faster to me.
