We have an existing Elasticsearch instance which is only accessible through an endpoint authenticated with OAuth. In our new Tridion Docs 13 SP2 installation, we are trying to configure or IQ Index Service to index via this Elasticsearch endpoint. However, looking at the documentation, it seems this may not be possible, as the IQ Index Service configuration only allows the following:
OAuth typically works by first requesting a token and then using that token to connect to the main endpoint, which means the IQ Index Service would need to be configured with 2 endpoints (token + Elasticsearch instance), but the configuration only allows for one (es.host:es.port). So does anyone know if it is possible to connect the IQ Index Service to Elasticsearch, in this scenario? And if so, how?
