- Added a record with "bul" in 008pos35-37
- Verified that this did not turn up in an advanced search with language =
  Bulgarian
- Applied the patch
- I was testing on a gitified install, so I had to copy the patched index file
  to the right location with this command:

sudo cp etc/zebradb/marc_defs/normarc/biblios/biblio-zebra-indexdefs.xsl \
/etc/koha/zebradb/marc_defs/normarc/biblios/biblio-zebra-indexdefs.xsl

- Did a full reindex
- Verified that the record *did* turn up in an advanced search with language =
  Bulgarian
- Signing off! Thanks Zeno!
