I found the solution to the issue. I added the output lookup field as additional accelerated field in the kvstore lookup. in my collections.conf, I previously had something like this: [test_kv] accelerated_fields.test1 = {"inputfield1": 1, "inputfield2": 1} Since the automatic lookups are using those two lookup fields like this: lookup test_kv_lookup inputfield1 inputfield2 OUTPUT outputfield1 I changed it to the following: accelerated_fields.test1 = {"inputfield1": 1, "inputfield2": 1, "outputfield1":1} accelerated_fields.test2 = {"outputfield1": 1, "inputfield1": 1, "inputfield2":1} Even though I don't need to do lookup by field "outputfield1", this will ensure that my searches without summariesonly=true will do a quick check to ensure that value I'm searching for is in the kvstore or not without having to load the entire lookup which takes like 20 minutes to do. Maybe there is a better way to do this, but this resolved the issue for me. ... View more
