Query that findall of a tag that does not incude another tag?

[OogieM]

I'm trying to create a dataview table query that will list all notes with a specific tag except those that aslo have another specific tag.

My YAML frontmater includes one of these 2 blocks (note there are often aliases and other tags as well)

`---
publish: false
aliases: [ ]
tags:

• project
• recurring
  ---`

or
`---
publish: false
aliases: [ ]
tags:

• project
  ---`

My dataview query so far is

dataview TABLE startdate as "Date" FROM #project where endate = null
But I want to add something like and tag != recurring so that my repeating checklist type projects do not show up in this view

I'm not finding a way to do a does not include type statemnt for a tag. Am I missing something obvious?

Solved by making the tags hierarchical with project/recurring, project/active, project/archive, project/hold and then the queries to get each type are like this:

dataview
TABLE startdate as "Date" 
FROM #project/recurring
WHERE endate = null  
SORT file.name ASC
