When enable_index_contained_resource is set to true, the 'exact:' operator under chain queries is invalid

[PhilipsYangZeLin]

step 1: Set enable_index_contained_resource to ture

step 2: Start the fhir service using the 'mvn - Djetty. port=8080 jetty: run command

step 3: Add a set of basic data for testing, including ServiceRequest resources and Patient resources

step 4: Use this URL to execute a query: http:https://localhost:8080/fhir/ServiceRequest?patient.name:exact=Peter&_include=ServiceRequest:subject

The patient name of result is 'Peter James' instead of 'Peter'

But when I set 'enable_index_contained_resource' to false, using the same URL query will not yield any results unless I query 'Peter James', which means the' exact 'operator is in effect
