Possible to fetch only tags?

[devteam (Digital Six)]

We would like to fetch a list of all tags used by a particular document type, as we were planning on using tags to show filters for the data. We were using the tags returned in the initial API response, but this seems to be being deprecated:

Prismic Blog

The natural replacement for this would be to include all used tags in the query header. Sadly, my query to try and fetch just the tags seems to be returning all data from all documents:

$query = [];
$query[] = Predicates::at(
    'document.type',
    $documentType
);
$options = ['fetch'=> 'document.tags'];
$response = $api->query($query, $options);

Is there a proper way to fetch this info? Is there a way to exclude documents that have no tags?

I have followed up with this issue, and what we recommend you for your use-case to index our documents data in a tool like Algolia or Elastic,

that will take care of implementing the filter + Search logic and mechanism.

Here is an exmaple that migh help
