+## Filtering log messages based on content
+
+Filelog receiver provides support for filtering logs based on their content. This can be achieved by using
+the [filter operator](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/pkg/stanza/docs/operators/filter.md),
+configured with matching regular expressions.
+
+With this happening at the collection point, a lot of resources at the destination backend
+can be saved since no additional processing would need to take place.
+
+A full configuration example on how to filter out logs that start with the `INFO:` pattern is
+provided in the [example config](./otel-col-config-filter-out-logs.yaml).
+A full configuration example on how to only collect logs that start with the `WARN:` pattern is provided in
+the [example config](./otel-col-config-filter-in-logs.yaml)
