Hello guyz , I have created an index with a custom analyzer having a filter for autocompletion . Now i also want to add tokenizer for Synonyms to my index . I always need to delete the index mapping and then again create new index for new setting . Is it possible to update mapping without deleting the index and apply it to the already stored records also . -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
