-## Schema Service adoption <a name="schema-service-adoption"></a>
-
-Indexer service is in adaptation process to use schemas from the Schema service instead of Storage Service. The Indexer
-Service retrieves a schema from the Schema Service if the schema is not found on the Storage Service. Change affects
-only Azure implementation so far. Later call to the Storage Service will be deprecated and then removed (after the end
-of the deprecation period).

-### R3 Schema Support <a name="r3-schema-support"></a>
-
-Indexer service support r3 schema. These schemas are created via Schema service.
-
-Here is an example following end-to-end workflow can be exercised (please update the schema based on your environment):
-
-- Ingest r3 schema for `opendes:wks:master-data--Wellbore:1.0.0`. Schema service payload can be
-  found [here](https://community.opengroup.org/osdu/platform/system/indexer-service/-/blob/master/testing/indexer-test-core/src/main/resources/testData/r3-index_record_wks_master.schema.json)
-  .

-- Ingest r3 master-data Wellbore record. Storage service payload can be
-  found [here](https://community.opengroup.org/osdu/platform/system/indexer-service/-/blob/master/testing/indexer-test-core/src/main/resources/testData/r3-index_record_wks_master.json)
-
-- Records can be searched via Search service. Here is sample payload:
-
-```
-POST /api/search/v2/query HTTP/1.1
-Content-Type: application/json
-data-partition-id: opendes
-{
