I have a custom field to be Indexed for each Item. If it does not get the value it returns
Before when Item's searched in Solr, whose custom fields are string.empty the field was not present in the item. But recently after Indexing for an item, the custom field with empty string is coming in the Solr.
So suppose my custom field name is
custom_fac_s. earlier when Solr is queried like:
custom_fac_s: "", it did not return any item, but recently it does.
Is there a change in Solr Behaviour?
I am using Sitecore 9.
The field is mapped in
Sitecore.ContentSearch.SolrProvider.SolrIndexConfiguration.config as below:
<field fieldName="Custom_Fac" storageType="yes" returntype="string" indexType="untokenized">extensions.Search.AddCustomFacetIndexField,extensions</field>
