+Where are read concern and write concern?
+-----------------------------------------
+
+These commands internally proxy the search index management commands to a separate process that runs alongside an Atlas cluster.  As such, read concern and 
+write concern are not relevant for the search index management commands.
+
+Consistency with Existing APIs
+------------------------------
+
+Drivers SHOULD strive for a search index management API that is as consistent as possible with their existing index management API.
+
+NamespaceNotFound Errors
+------------------------
+
+Some drivers suppress NamespaceNotFound errors for CRUD helpers.  Drivers MAY suppress NamespaceNotFound errors from 
+the search index management helpers.
+
+Drivers MUST suppress NamespaceNotFound errors for the ``dropSearchIndex`` helper.  Drop operations should be idempotent:

+Search Index Management Helpers
+-------------------------------
+
+These tests are intended to smoke test the search management helpers end-to-end against a live Atlas cluster.
+
+The search index management commands are asynchronous and mongod/mongos returns before the changes to a clusters' search indexes have completed.  When
+these prose tests specify "waiting for the changes", drivers should repeatedly poll the cluster with ``listSearchIndexes``
+until the changes are visible.  Each test specifies the condition that is considered "ready".  For example, when creating a 
+new search index, waiting until the inserted index has a status ``queryable: true`` indicates that the index was successfully
+created.
+
+The commands tested in these prose tests take a while to successfully complete.  Drivers should raise the timeout for each test to avoid timeout errors if 
+the test timeout is too low.  5 minutes is a sufficiently large timeout that any timeout that occurs indicates a real failure, but this value is not required and can be tweaked per-driver.
+
+There is a server-side limitation that prevents multiple search indexes from being created with the same name, definition and 
+collection name.  This limitation does not take into account collection uuid.  Because these commands are asynchronous, any cleanup
+code that may run after a test (cleaning a database or dropping search indexes) may not have completed by the next iteration of the 
+test (or the next test run, if running locally).  To address this issue, each test uses a randomly generated collection name.  Drivers
+may generate this collection name however they like, but a suggested implementation is a hex representation of an
+ObjectId (``new ObjectId().toHexString()`` in Node).
+
+Setup
+~~~~~
+
+These tests must run against an Atlas cluster with a 7.0+ server.  `Scripts are available <https://github.com/mongodb-labs/drivers-evergreen-tools/tree/master/.evergreen/atlas>`_ in drivers-evergreen-tools which can setup and teardown
+Atlas clusters.  To ensure that the Atlas cluster is cleaned up after each CI run, drivers should configure evergreen to run these tests 
+as a part of a task group.  Be sure that the cluster gets torn down! 
+
+When working locally on these tests, the same Atlas setup and teardown scripts can be used locally to provision a cluster for development.
+
+Case 1: Driver can successfully create and list search indexes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Create a collection with the "create" command using a randomly generated name (referred to as ``coll0``).
+#. Create a new search index on ``coll0`` with the ``createSearchIndex`` helper.  Use the following definition:
+
+  .. code:: typescript
+
+    {
+      name: 'test-search-index',
+      definition: {
+        mappings: { dynamic: false }
+      }
+    }
+
+#. Assert that the command returns the name of the index: ``"test-search-index"``.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until the following condition is satisfied and store the value in a variable ``index``:
+   1. An index with the ``name`` of ``test-search-index`` is present and the index has a field ``queryable`` with a value of ``true``.
+
+#. Assert that ``index`` has a property ``latestDefinition`` whose value is ``{ 'mappings': { 'dynamic': false } }``
+
+Case 2: Driver can successfully create multiple indexes in batch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Create a collection with the "create" command using a randomly generated name (referred to as ``coll0``).
+#. Create two new search indexes on ``coll0`` with the ``createSearchIndexes`` helper.  Use the following
+   definitions when creating the indexes.  These definitions are referred to as ``indexDefinitions``.
+
+  .. code:: typescript
+
+    {
+      name: 'test-search-index-1',
+      definition: {
+        mappings: { dynamic: false }
+      }
+    }
+    {
+      name: 'test-search-index-2',
+      definition: {
+        mappings: { dynamic: false }
+      }
+    }
+
+#. Assert that the command returns an array containing the new indexes' names: ``["test-search-index-1", "test-search-index-2"]``.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until the following condition is satisfied.
+   1. An index with the ``name`` of ``test-search-index-1`` is present and index has a field ``queryable`` with the value of ``true``. Store result in ``index1``.
+   2. An index with the ``name`` of ``test-search-index-2`` is present and index has a field ``queryable`` with the value of ``true``. Store result in ``index2``.
+#. Assert that ``index1`` and ``index2`` have the property ``latestDefinition`` whose value is ``{ "mappings" : { "dynamic" : false } }``
+Case 3: Driver can successfully drop search indexes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Create a collection with the "create" command using a randomly generated name (referred to as ``coll0``).
+#. Create a new search index on ``coll0`` with the following definition:
+
+  .. code:: typescript
+
+    {
+      name: 'test-search-index',
+      definition: {
+        mappings: { dynamic: false }
+      }
+    }
+
+#. Assert that the command returns the name of the index: ``"test-search-index"``.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until the following condition is satisfied:
+   1. An index with the ``name`` of ``test-search-index`` is present and index has a field ``queryable`` with the value of ``true``.
+
+#. Run a ``dropSearchIndex`` on ``coll0``, using ``test-search-index`` for the name.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until ``listSearchIndexes`` returns an empty array.
+
+This test fails if it times out waiting for the deletion to succeed.
+
+Case 4: Driver can update a search index
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Create a collection with the "create" command using a randomly generated name (referred to as ``coll0``).
+#. Create a new search index on ``coll0`` with the following definition:
+
+  .. code:: typescript
+
+    {
+      name: 'test-search-index',
+      definition: {
+        mappings: { dynamic: false }
+      }
+    }
+
+#. Assert that the command returns the name of the index: ``"test-search-index"``.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until the following condition is satisfied:
+   1. An index with the ``name`` of ``test-search-index`` is present and index has a field ``queryable`` with the value of ``true``.
+
+#. Run a ``updateSearchIndex`` on ``coll0``, using the following definition.
+
+  .. code:: typescript
+
+    {
+      name: 'test-search-index',
+      definition: {
+        mappings: { dynamic: true }
+      }
+    }
+
+#. Assert that the command does not error and the server responds with a success.
+#. Run ``coll0.listSearchIndexes()`` repeatedly every 5 seconds until the following condition is satisfied:
+   1. An index with the ``name`` of ``test-search-index`` is present.  This index is referred to as ``index``.
+   2. The index has a field ``queryable`` with a value of ``true`` and has a field ``status`` with the value of ``READY``.
+
+#. Assert that an index is present with the name ``test-search-index`` and the definition has a
+  property ``latestDefinition`` whose value is ``{ 'mappings': { 'dynamic': true } }``.
+
+Case 5: ``dropSearchIndex`` suppresses namespace not found errors
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Create a driver-side collection object for a randomly generated collection name.  Do not create this collection on the server.
+#. Run a ``dropSearchIndex`` command and assert that no error is thrown.
