I need to update Solr schema for text highlighting using code.

What is the way to update Solr schema using code in Sitecore 10.3?

Since 'SolrProvider.GetHelper is obsolete'

It's all described in Sitecore documentation here:


In shortcut:

  • You need to create your own ISchemaPopulateHelper implementation, best by overriding SchemaPopulateHelper, e.g.
public class CustomPopulateHelper : SchemaPopulateHelper
    public CustomPopulateHelper(SolrSchema schema) : base(schema)
  • And your own factory like:
public class CustomPopulateHelperFactory : IPopulateHelperFactory
    public ISchemaPopulateHelper GetPopulateHelper(SolrSchema solrSchema)
        return new CustomPopulateHelper(solrSchema);
  • Then register the factory in patch file:
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
        <processor type="Sitecore.ContentSearch.SolrProvider.Pipelines.PopulateSolrSchema.PopulateFields, Sitecore.ContentSearch.SolrProvider">
       <param type="Documentation.Examples.CustomPopulateHelperFactory, Documentation.Examples" patch:instead="*[@type='Sitecore.ContentSearch.SolrProvider.Factories.DefaultPopulateHelperFactory']"/>
  • It is helpful can you please suggest how can we get index name in this implementation Aug 9 at 12:29
