I created a SOLR query to find the news that has a tag of the category "EVENTS" without necessarily having the tag "EVENTS".

site:www-ville AND contentLanguage:fr AND allTags:EVENEMENTS AND end-date_dt:[NOW-1DAY TO *]

I do not get contents that have a tag of the category, example: I have the tag "CULTURE" but not the mother tag "EVENTS".
If I assign the "EVENTS" tag to the content, I restart my search, the content appears, if I remove the tag the content always appears in the results.

If I create a new news content with the tag "CULTURE" but not "EVENTS" it will appear directly in the results
