I did a setup of sample Sitecore Instance (sc82solr), and followed the configuration from the following link
Found the Solr is working fine.
When I browse the Sitecore Site (sc82solr), I am getting the error like below ?
Could not find configuration node: contentSearch/indexConfigurations/defaultLuceneIndexConfiguration/fieldMap
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Could not find configuration node: contentSearch/indexConfigurations/defaultLuceneIndexConfiguration/fieldMap
Can someone suggest, what could be the issue ?
