Hibernate 使用 opendistro 搜索 6.0.2.Final

Question

I have a Spring Boot 2.4.2 application integrated with Hibernate Search 6.0.2.Final

When using standard elasticsearch everything works fine (read/write) on persisting new entities. The index also gets created as expected myindex-000001 based on the default simple index strategy.

However, when I switched the backend to opendistro (latest) I only see a single index created by the name myindex-write (different that the expected myindex-000001 ). The write operations work fine as expected (due to the suffix -write ), however the read operations fail with the error:

root_cause": [
      {
        "type": "index_not_found_exception",
        "reason": "no such index [myindex-read]",
        "resource.type": "index_or_alias",
        "resource.id": "myindex-read",
        "index_uuid": "_na_",
        "index": "myindex-read"
      }
    ]

GET /_cat/aliases on opendistro show that there are no aliases for the index.

What is the best possible way to resolve this? no-alias strategy shown here ? The downside of using no-alias is the lack of blue-green deployment like re-indexing. Is custom index strategy the best way to solve this?

Answer 1

All the above issues were caused because I had set hibernate.search.schema_management.strategy to none . The indexes need to be created manually, as mentioned in the docs here
