I forgot to index a field called "n_citation" which is in type "integer".
When mapping the dataset, I decide to map the necessary fields (like "title" and "abstract") only to save my time. Now, it turns out that the "n_citation" field is important(maybe the most important field). I have 500GB dataset to map. What should I do now? Is there a quick way to reindex it?
If the field is not part of the
_source document yet, you need to reindex everything from the source as you initially did it.
If the field is part of it, you can may be use the
_reindex API and just change the target index mapping.
thanks for the awesome information.
