"Index sitecore_suggested_test_index was not found" on CM 8.2 after changing the default Solr index name

Question

I am running:

• 8.2 Update 7
• Solr
• xDB and Tracking enabled

The Solr instance is shared across DEV and QA, so I need to prefix the index names for all of the indexes so that they do not conflict.

I have done this with patch config files and Azure DevOps pipeline replacement variables per environment that prepend an environment specific value for all indexes.

So, the sitecore_suggested_test_index index for DEV and QA live side by side on the same Solr instance as dev_sitecore_suggested_test_index and "a_sitecore_suggested_test_index respectively.

I have patched the following:

<index type="Sitecore.ContentSearch.SolrProvider.SolrSearchIndex, Sitecore.ContentSearch.SolrProvider" patch:source="zIndexes.config" id="82u7_sitecore_suggested_test_index">

<setting name="ContentTesting.SuggestedTestIndexName" patch:source="zIndexes.config" value="82u7_sitecore_suggested_test_index"/>

On my CM+Processing server for each environment, I am seeing the following error:

ManagedPoolThread #4 18:09:58 ERROR Error executing schedule item: Rebuild Suggested Tests Index

Exception: Sitecore.ContentSearch.Exceptions.IndexNotFoundException
Message: Index sitecore_suggested_test_index was not found
Source: Sitecore.ContentSearch
   at Sitecore.ContentSearch.ContentSearchManager.GetIndex(String name)

The value sitecore_suggested_test_index by itself without the prefix does not appear anywhere in the showconfig.aspx output.

Where else is the name of this index configured?

Answer 1

The name of this index is also specified in the master database separately from configuration files. In order to properly rename this index, you must also update the Index Name field on the following item:

/sitecore/system/Tasks/Commands/Content Testing/Rebuild Suggested Tests Index
