Hi, I would like to further understand indices in search db that have the word -suggest- in its name?

  • What is the purpose of these indices?
  • Why do they have a lower replication factor of 1 compared to other indices?
  • Is it correct understanding these indices are not mandatory and dispensable? e.g.: if we lose a '-suggest-' index due to nodes being unavailable DataMiner carries on working with no data loss and new -suggest- index gets re-created.

Hi Bing,

From the documentation in Index types | DataMiner Docs, the indices of type [prefix]-suggest- contain data for enhanced search suggestions and can usually be omitted without affecting other parts of the software.

Additionally, from 10.4 onwards, some of these indices have been removed as documented in General Main Release 10.4.0 – Changes - Elasticsearch/OpenSearch: Unused suggest indices have been disabled | DataMiner Docs.
