@ -10,6 +10,30 @@ To use built-in search that has no external dependencies, set the search module

 While it has no external dependencies, it has problems with performance and relevancy.

+## QdrantSearch
+
+This uses the vector search engine [Qdrant](https://qdrant.tech) to search the posts in a vector space. This needs a way to generate embeddings and uses the [OpenAI API](https://platform.openai.com/docs/guides/embeddings/what-are-embeddings). This is implemented by several project besides OpenAI itself, including the python-based fastembed-server found in `supplemental/search/fastembed-api`.
+
+The default settings will support a setup where both the fastembed server and Qdrant run on the same system as pleroma. To use it, set the search provider and run the fastembed server, see the README in `supplemental/search/fastembed-api`:
+
+> config :pleroma, Pleroma.Search, module: Pleroma.Search.QdrantSearch
+
+Then, start the Qdrant server, see [here](https://qdrant.tech/documentation/quick-start/) for instructions.
+
+You will also need to create the Qdrant index once by running `mix pleroma.search.indexer create_index`. Running `mix pleroma.search.indexer index` will retroactively index the last 100_000 activities.
+
+### Indexing and model options
+
+To see the available configuration options, check out the QdrantSearch section in `config/config.exs`.
+
+The default indexing option work for the default model (`snowflake-arctic-embed-xs`). To optimize for a low memory footprint, adjust the index configuration as described in the [Qdrant docs](https://qdrant.tech/documentation/guides/optimize/). See also [this blog post](https://qdrant.tech/articles/memory-consumption/) that goes into detail.
+
+Different embedding models will need different vector size settings. You can see a list of the models supported by the fastembed server [here](https://qdrant.github.io/fastembed/examples/Supported_Models), including their vector dimensions. These vector dimensions need to be set in the `qdrant_index_configuration`. 
+
+E.g, If you want to use `sentence-transformers/all-MiniLM-L6-v2` as a model, you will not need to adjust things, because it and `snowflake-arctic-embed-xs` are both 384 dimensional models. If you want to use `snowflake/snowflake-arctic-embed-l`, you will need to adjust the `size` parameter in the `qdrant_index_configuration` to 1024, as it has a dimension of 1024.
+
+When using a different model, you will need do drop the index and recreate it (`mix pleroma.search.indexer drop_index` and `mix pleroma.search.indexer create_index`), as the different embeddings are not compatible with each other.

-# Prometheus Metrics
+# Prometheus / OpenTelemetry Metrics

-Pleroma includes support for exporting metrics via the [prometheus_ex](https://github.com/deadtrickster/prometheus.ex) library.
+Pleroma includes support for exporting metrics via the [prom_ex](https://github.com/akoutmos/prom_ex) library.
+The metrics are exposed by a dedicated webserver/port to improve privacy and security.

 Config example:

 ```
-config :prometheus, Pleroma.Web.Endpoint.MetricsExporter,
-  enabled: true,
-  auth: {:basic, "myusername", "mypassword"},
-  ip_whitelist: ["127.0.0.1"],
-  path: "/api/pleroma/app_metrics",
-  format: :text
-```
-
-* `enabled` (Pleroma extension) enables the endpoint
-* `ip_whitelist` (Pleroma extension) could be used to restrict access only to specified IPs
-* `auth` sets the authentication (`false` for no auth; configurable to HTTP Basic Auth, see [prometheus-plugs](https://github.com/deadtrickster/prometheus-plugs#exporting) documentation)
-* `format` sets the output format (`:text` or `:protobuf`)
-* `path` sets the path to app metrics page 
-
-
-## `/api/pleroma/app_metrics`
-
-### Exports Prometheus application metrics
-
-* Method: `GET`
-* Authentication: not required by default (see configuration options above)
-* Params: none
-* Response: text
-
-## Grafana
-
-### Config example
-
-The following is a config example to use with [Grafana](https://grafana.com)
+config :pleroma, Pleroma.PromEx,
+  disabled: false,
+  manual_metrics_start_delay: :no_delay,
+  drop_metrics_groups: [],
+  grafana: [
+    host: System.get_env("GRAFANA_HOST", "http://localhost:3000"),
+    auth_token: System.get_env("GRAFANA_TOKEN"),
+    upload_dashboards_on_start: false,
+    folder_name: "BEAM",
+    annotate_app_lifecycle: true
+  ],
+  metrics_server: [
+    port: 4021,
+    path: "/metrics",
+    protocol: :http,
+    pool_size: 5,
+    cowboy_opts: [],
+    auth_strategy: :none
+  ],
+  datasource: "Prometheus"

 ```
-  - job_name: 'beam'
-    metrics_path: /api/pleroma/app_metrics
-    scheme: https
+
+PromEx supports the ability to automatically publish dashboards to your Grafana server as well as register Annotations. If you do not wish to configure this capability you must generate the dashboard JSON files and import them directly. You can find the mix commands in the upstream [documentation](https://hexdocs.pm/prom_ex/Mix.Tasks.PromEx.Dashboard.Export.html). You can find the list of modules enabled in Pleroma for which you should generate dashboards for by examining the contents of the `lib/pleroma/prom_ex.ex` module.
+
+## prometheus.yml
+
+The following is a bare minimum config example to use with [Prometheus](https://prometheus.io) or Prometheus-compatible software like [VictoriaMetrics](https://victoriametrics.com).
+
+```
+global:
+  scrape_interval: 15s
+
+scrape_configs:
+  - job_name: 'pleroma'

    static_configs:

+  Dynamic activity filtering based on an RBL database
+
+  This MRF makes queries to a custom DNS server which will
+  respond with values indicating the classification of the domain
+  the activity originated from. This method has been widely used
+  in the email anti-spam industry for very fast reputation checks.
+
+  e.g., if the DNS response is 127.0.0.1 or empty, the domain is OK
+  Other values such as 127.0.0.2 may be used for specific classifications.
+
+  Information for why the host is blocked can be stored in a corresponding TXT record.
+
+  This method is fail-open so if the queries fail the activites are accepted.
+
+  An example of software meant for this purpsoe is rbldnsd which can be found
+  at http://www.corpit.ru/mjt/rbldnsd.html or mirrored at
+  https://git.pleroma.social/feld/rbldnsd
+
+  It is highly recommended that you run your own copy of rbldnsd and use an
+  external mechanism to sync/share the contents of the zone file. This is
+  important to keep the latency on the queries as low as possible and prevent
+  your DNS server from being attacked so it fails and content is permitted.
