Closed aulemahal closed 1 year ago

aulemahal commented 1 year ago

Change Summary

_search.search will use df[column].isnull() if column=None has been passed. np.NaN and pd.NA or anything that pd.isna(value) is suported.

Related issue number

Fixes #611.

Checklist

[x] Unit tests for the changes exist
[x] Tests pass on CI
[ ] Documentation reflects the changes where applicable

There are two added search tests because the case None was raising an error is QueryModel, while np.nan (which is a float) was not.
