--- Comment #54 from David Gustafsson <glasklas at gmail.com> ---
Thanks for the review and good suggestions. I agree the hybrid method seems the
best, could also save a marc_format so format does not have to be detected.

I have also considered the two option you mentioned, storing the whole marc
record as json or skip storing it all together. The later could possibly be an
option (for those wanting to keep index size small), the former would be really
and would like to see implemented so could be the subject for a future bug. The
catamandu json serialization format is pretty useless for querying and
analysis, but it probably not take that much work to write a marc to json
direct conversion which allowed you to make queries like 100.a:"Tolkien, J. R.
R.". I would also like to use Kibana for analysis and for that to be useful you
would have t have the marc data available as structured json.
