when developing a new logstash filter, I initially by mistake got fields mapped as string rather than number, now I want to search out all the docIDs where specific fields are of type string rather than numbers so I can search my docs from Kibana and avoid this warning from Kibana:
Mapping conflict! 6 fields are defined as several types (string, integer, etc) across the indices that match this pattern. You may still be able to use these conflict fields in parts of Kibana, but they will be unavailable for functions that require Kibana to know their type. Correcting this issue will require reindexing your data
Q is just howto do this, hints are much appreciated!
