Hi everyone 
We recently introduced the Search Demo Builder, a new tool in the Atlas Search Playground that lets you explore and configure search features in a low-code GUI without needing an Atlas account. With a preloaded dataset or your own uploaded data, the tool allows you to experiment with features like autocomplete and facets via an interactive preview and auto-generates the corresponding index and query definitions.
For more details, check out the official docs page or the announcement on the MongoDB blog. And if you have feedback or ideas you can let us know here.
