Description

When configuring Sitecore 8 to use Solr as a search provider, an error similar to the following one may appear:

[InvalidOperationException: Could not find property 'typeMatches' on object of type: Sitecore.ContentSearch.SolrProvider.SolrFieldMap]
    Sitecore.Diagnostics.Assert.IsTrue(Boolean condition, String message) +57
    Sitecore.Configuration.Factory.AssignProperties(Object obj, Object[] properties) +330
    Sitecore.Configuration.Factory.AssignProperties(XmlNode configNode, String[] parameters, Object obj, Boolean assert, Boolean deferred, IFactoryHelper helper) +759
    Sitecore.Configuration.Factory.CreateObject(XmlNode configNode, String[] parameters, Boolean assert, IFactoryHelper helper) +296
    Sitecore.Configuration.Factory.GetInnerObject(XmlNode paramNode, String[] parameters, Boolean assert) +117
    ...
    Sitecore.ContentSearch.ContentSearchManager.get_SearchConfiguration() +261
    Sitecore.ContentSearch.SolrProvider.SolrContentSearchManager.get_Cores() +77
    Sitecore.ContentSearch.SolrProvider.CastleWindsorIntegration.WindsorSolrStartUp.Initialize() +57

This issue is caused by incorrect search index configuration in the /App_Config/Include/FXM/Sitecore.FXM.Solr.Index.DomainsSearch.config file.

Solution

Replace the original /App_Config/Include/FXM/Sitecore.FXM.Solr.Index.DomainsSearch.config file with a new one:
Sitecore.FXM.Solr.Index.DomainsSearch.config
