New search index stuck in "Not Started" state

Hello,

We are creating a search index for text search, but the index on the primary node is stuck in “Not Started” state for 2 days.

We already have a default search index “Active” for the same collection. And we have the same index already “Active” for other collections.

We made sure that the index is valid and there are free resources in the cluster. We don’t see any errors or warnings.

Is there a way to have more insights about what is going on, or why it is not moving forward with the index creation?
