Get all Term data from database by Term field and data.Warning: $value is not escaped for 'name' $field. You must do it yourself, if
The default $field is 'id', therefore it is possible to also use null for
field, but not recommended that you do so.
If $value does not exist, the return value will be false. If $taxonomy exists
and $field and $value combinations exist, the Term will be returned.
This function will always return the first term that matches the `$field`-
`$value`-`$taxonomy` combination specified in the parameters. If your query
is likely to match more than one term (as is likely to be the case when
`$field` is 'name', for example), consider using get_terms() instead; that
way, you will get all matching terms, and can provide your own logic for
deciding which one was intended.
