[yt-dev] What would be useful for coarse-grained indexing?

Hi all,

In this PR I've tried to instigate a discussion of what would be useful for a coarse-grained index of datasets:

https://bitbucket.org/yt_analysis/yt/pull-requests/1902/rfc-yt-search-comman...

For the "minimum representation" object, we use:

("dimensionality", "refine_by", "domain_dimensions", "current_time", "domain_left_edge", "domain_right_edge", "unique_identifier", "current_redshift", "output_hash", "cosmological_simulation", "omega_matter", "omega_lambda", "hubble_constant", "name")

Is this sufficient, or should we add/remove things? We likely want to remove the cosmological ones from non-cosmo sims (and leave them in for cosmo sims) but otherwise, is there anything else we should include?
