We are just getting started with App Search. I think the answer is no, but in case we are missing something....
Does App Search support bitwise comparisons? For example, could we store a bunch of values in one field as a bitmap and then do a bitwise comparison to see if a value exists?
App Search has a 64 field limit. Is it possible to add more fields to the underlying Elasticsearch index, but only have App Search use the 64 fields it knows about? For those other fields, we would hit Elasticsearch directly.
In Elasticsearch, you can have runtime fields that can be the result of a script. Does that functionality exist in App Search?
Also, when sorting by name, "ARM Holdings plc" comes up before "Aetna Inc". Does App Search sort an all capital word before proper cased words?
