## Installation{% #installation %}

Run your service with Dynamic Instrumentation enabled, and additionally enable autocomplete and search:

1. Set the `DD_SYMBOL_DATABASE_UPLOAD_ENABLED=true` environment variable.
1. Specify the `DD_SERVICE` and `DD_VERSION` [Unified Service Tags](https://docs.datadoghq.com/getting_started/tagging/unified_service_tagging).

## Additional configuration{% #additional-configuration %}

### Third party detection{% #third-party-detection %}

If autocomplete suggestions do not appear for your package or module, it may be incorrectly recognized as third-party code. The autocomplete and search features use a heuristic to filter out third-party code, which can sometimes lead to accidental misclassification.

To ensure that your code is properly recognized and to enable accurate autocomplete and search functionality, you can configure the third-party detection settings using the following options:

```shell
export DD_THIRD_PARTY_EXCLUDES=<LIST_OF_USER_CODE_PACKAGE_PREFIXES>
export DD_THIRD_PARTY_INCLUDES=<LIST_OF_ADDITIONAL_THIRD_PARTY_PACKAGE_PREFIXES>
```

Where a list means a comma separated list of package prefixes, for example:

```shell
export DD_THIRD_PARTY_EXCLUDES=com.mycompany,io.mycompany
```
