Configuration: Sitecore 9.0.2, Azure PaaS
As most of us know by now, Azure Search has a hard limit on the number of fields that can be added to an index (1000). To resolve this issue in our environment, I developed the following patch file:
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:search="http://www.sitecore.net/xmlconfig/search/"> <sitecore role:require="Standalone or ContentDelivery or ContentManagement" search:require="Azure"> <contentSearch> <configuration> <indexes> <index id="sitecore_master_index"> <configuration> <documentOptions ref="contentSearch/indexConfigurations/defaultCloudIndexConfiguration/documentOptions"> <!-- We only want default fields in the core/master/web indexes on azure due to 1000 field limit --> <indexAllFields>false</indexAllFields> <!-- Fix sitecore 9 forms issue 229445 --> <include hint="list:AddIncludedField"> <isTemplate>{558F9307-EBAF-480D-88B5-DFE9E63A66DE}</isTemplate> <hidden>{39C4902E-9960-4469-AEEF-E878E9C8218F}</hidden> </include> <include hint="list:AddIncludedField"> <my_custom_field>{EA795E6C-46E5-48B0-ACDA-E7288A018646}</my_custom_field> <!-- ... other fields omitted for brevity ... --> </include> </documentOptions> </configuration> </index> </indexes> </configuration> </contentSearch> </sitecore> </configuration> As you can see, I've disabled indexAllFields and explicitly included only those that we need.
However, when we run an index rebuild I'm still getting the below error in the logs:
ERROR [Index=sitecore_master_index] Commit failed
[...]
Nested Exception
Exception: Sitecore.ContentSearch.Azure.Http.Exceptions.AzureSearchServiceRESTCallException
Message: {"error":{"code":"","message":"The request is invalid. Details: definition : Invalid index: The index contains 1004 leaf fields (fields of a non-complex type). An index can have at most 1000 leaf fields.\r\n"}}
I looked in Azure and confirmed that my index has many other fields that I haven't included in my config. Why are these fields still being added?
