Hi, Barry. That wording is a little confusing … instead of a list, the
"inputs" field should be a JSON object like:
{"bucket":"mybucket",
"index":"myindex_bin",
"key":"my exact match"}
or
{"bucket":"mybucket",
"index":"myindex_int",
"start":0
"end":100}
More complete examples are near the bottom of
