+`REDUCE COLLECT` is gated behind the server's *unstable features* flag; the feature and its API may be subject to change.
+
+*COLLECT* is an `FT.AGGREGATE` reducer that gathers per-document projections within a `GROUPBY` group and returns them
+as an array of per-entry maps under the reducer alias, optionally sorted and bounded.
+
+The server does not expose it by default: it must be enabled explicitly, for example via
+
+```
+CONFIG SET search-enable-unstable-features yes
+```
+
+In a cluster the coordinator fans the query out to every shard, so the flag must be enabled on all nodes rather than
+only the one a given connection happens to route to. Without it, the server replies with an error.
+
+The corresponding library feature must also be considered subject to change:
+
+1. Existing bindings may cease working correctly if the underlying server API changes.
+2. Changes to the server API may require changes to the library API, manifesting in either/both of build-time
+   or run-time breaks.
+
+Because the server itself still classes this as an unstable feature, such changes are rather more likely here than for
+a feature that has simply not been out for long. If you acknowledge this, you can suppress this warning by adding the
+following to your `csproj` file:
+
+```xml
+<NoWarn>$(NoWarn);NRS003</NoWarn>
+```
+
+or more granularly / locally in C#:
+
+```c#
+#pragma warning disable NRS003
+```
