#Version

Mtas provides a method to display information about `artifactId`, `groupId`, `version` and `timestamp` from the build.  

To include this information, in Solr requests, besides the parameter to enable the [Mtas query component](search_component.html), the following parameter should be provided.

| Parameter             | Value  | Obligatory  |
|-----------------------|--------|-------------|
| mtas.version          | true   | yes         |
