Substring matches?

[jeffdlb]

Hi @andersy005:

I hope all is well with you in these strange times.

I believe with intake-esm one can search the collection only for entire column values, not substrings. E.g., I can find TAUX, TAUX2, or TAUY, but not "TAU*".

• Can substring matching be added?
• Is the absence of substring matching something that would need to be added by intake-esm, or by intake itself?

Unless I am mistaken, it seems that substring matching would be a one-line code change. In _get_subset() at https://github.com/NCAR/intake-esm/blob/master/intake_esm/core.py, on line 633 replace (df[key] == val_i) with (val_i in df[key])

This would be a case-sensitive match, so a bit of additional logic would be needed to ignore case.
