Hi everyone 
We recently introduced Atlas Search Query Templates as a new feature within Search Tester. With query templates, you now have access to 14 pre-written Search queries including conditional clauses like must and should, autocomplete for search-as-you-type experiences, faceting, and more.
You’ll find these query templates by logging into your Atlas account, clicking into the Search index you want to query, navigating to the Search Tester, and clicking “Edit Query” to open the JSON query editor.
We hope these query templates make it easier to start querying with Atlas Search. If you have feedback or ideas you can let us know here.
