I was trying to implement search functionality with Solr on Sitecore 10.1 instance. But I am not able to find the following default indexes:

  • sitecore_web_index
  • sitecore_master_index
  • sitecore_web_core

enter image description here

Some notes: i. Solr is up and running smoothly ii. All Solr config files inside app_config are enabled, (Examples folder, ContentSearch folder)

A snapshot of Solr cores: enter image description here

Are there any settings I'm missing? Any help would be highly appreciated. Thanks community for your immense help, I'm looking forward to a solution.

The above issue was caused by adding all the Solr config files which were present inside <instance>\App_Config\Include\Examples folder, which had these files:

  • Sitecore.ContentSearch.SolrCloud.SwitchOnRebuild.config
  • Sitecore.ContentSearch.Solr.SwitchOnRebuild.config

The above files overrode Solr default config files and switched to Solr cloud.
Thanks to @Cristy for his help. Disabling the Solr cloud configs fixed the issue.

Hope this helps anyone who is facing this issue.

  • Thanks Cristi for your help again, yes I have that file inside ContentSearch folder, which also includes Sitecore.ContentSearch.Solr.Index.Core.config, Sitecore.ContentSearch.Solr.Index.Master.config, Sitecore.ContentSearch.Solr.Index.Web.config

  • Can you verify in /sitecore/admin/Showconfig.aspx what configration you have for sitecore_master_index? And if you deployed all schemas to solr, I can see from printscreen that you have lindesc_? Mar 9, 2021 at 8:02
  • Try repopulating indexes and then restart solr Mar 9, 2021 at 8:03
  • @CristiVulturar While inspecting Showconfig.aspx, Im able to find sitecore_master_index inside patch:source="Sitecore.ContentSearch.SolrCloud.SwitchOnRebuild.config".

I assume that the file Sitecore.ContentSearch.Solr.Index.Master.config is present in the \App_Config\Sitecore\ContentSearch\ folder. When verifying with /sitecore/admin/ShowConfig.aspx page you should be seeing the definition of <index id="sitecore_master_index" in the configuration.

If you take a look at the definition of the indexes they all have <sitecore role:require="Standalone or ContentManagement" search:require="solr">, could you verify in web.config if you have <add key="search:define" value="Solr"/> set and <add key="role:define" value="Standalone"/>?

I am not sure why you have Sitecore.ContentSearch.SolrCloud.SwitchOnRebuild.config enabled, by default this file is disabled. If you take a look in it there are some <patch:delete /> for the sitecore_master index. If you don't have solrcloud you should comment out this file or try to use Sitecore.ContentSearch.Solr.SwitchOnRebuild.config instead.

  • Thanks Cristi, I have checked, <add key="role:define" value="Standalone"/> and <add key="search:define" value="Solr"/> are present in the web.config file

  • I updated the answer, please take a look at why you have Sitecore.ContentSearch.SolrCloud config enabled. Mar 9, 2021 at 11:03
  • Ah Thanks a lot @Cristi. You are like god of Sitecore to me ^_^ It worked, I just disabled the Sitecore.ContentSearch.SolrCloud.SwitchOnRebuild.config file, which I accidentally enabled following a Sitecore blog on the net. Thanks a lot for the help! Kudos!!

I had the same problem as you, but my solution was a little different so adding it here for future reference.

It turned out that these 3 files:


Found under "~\App_Config\Sitecore\ContentSearch" were getting overwritten by the custom solution ones of my project, and the <param desc="core">INSERTCOREINDEXNAME</param> field inside them looked like <param desc="core">{id}</param> rather than have the correct core name inside it

Once I fixed the 3 params to include the correct core names they showed up in my instance's index manager.
