Description

This is a migrated issue from previous Luke project in GitHub: https://github.com/DmitryKey/luke/issues/3 (There are users' requests so I moved this from GitHub to Jira)

You can browse terms in arbitrary field via Luke GUI, but in some cases "exporting all terms (and optionally docids) to a file" feature would be useful for further inspection. It might be similar to Solr's terms component.

As for the user interface, "Export terms" button should be located in Overview tab and/or Documents tab.
