How to ignore missing fields while reindexing in Elasticsearch

OliverWu · January 15, 2020, 8:14pm

If I have a destination index with only portion of source index, and I only want to reindex these fields from source index to destination index, Can I still using the reindex API or what should I do with this situation? Any solutions or suggestions thanks!

If I direct do reindex, the error is like Could not convert [fieldName] to boolean. fieldName is the missing field.
