[FEATURE] Add "suggest" to SearchResponse

[svenhartmann]

It looks like the SearchResponse is missing serialization for a suggestion response yet, e.g. https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#querying

Thanks for raising this @svenhartmann. The suggesters property had some issues with code-gen and is on a list for me to revisit. I'll keep this issue open to track that progress. For the second item, I'll need to investigate. That might be an issue with the spec.

@svenhartmann For the second item, the second code snippet is the correct way to configure the suggester. We model this in the spec as a specialised container concept, with FieldSuggester being able to contain one of the three possible suggester variants (completion, phrase and term). There is an issue with our spec as prefix (and regex) shouldn't appear on the CompletionSuggester variant. I'm going to split this into two issues so we can track and resolve each independently.

The usage for container types like FieldSuggester is something I'd like to improve in our code gen so that setting the container properties can be achieved with the factory methods. I have an issue #7400 capturing such improvements.

@stevejgordon Would be nice to have this feature and the range queries within the next release. Is it feasible?

[svenhartmann]

@stevejgordon Any news here?

[stevejgordon]

@svenhartmann I looked at this for 8.1.0, but we still need to do some work in code-gen to handle the spec and make the code usable. I don't have an ETA for when we will pick this up but agree it's a gap we need to fill.

@stevejgordon Seems that its not in the 8.1.1 release. I started migration of a webshop search of a customer in march and the only features that breaks the upgrade is the missing suggest response.

[stevejgordon]

@svenhartmann I didn't get a chance to focus on this for the latest release, so unfortunately, it is still open. I have moved on from maintaining this library day-to-day which has slowed progress, and we have a new engineer starting today to take ownership. We can't provide any timescales for this item at the moment, but it will be picked up when possible.

I am also migrating to the new client and are also blocked by this missing feature.

Hello, we are also trying to migrate to Elastic.Clients.Elasticsearch 8.1.x (to upgrade also from ES7 to ES8) and we also have this issue with the suggestions that is blocking our upgrade. Could we provide you some help ? If you give me some guidance, I can take a look to fix that issue?
