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

[Matthew Turk]

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-command

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?
