Does anyone know how to filter by strategy on NCBI's search in BioProject/SRA? (e.g., no amplicons)

Question

[O.rka]

I'm trying to search BioProjects that have shotgun metagenomics based on some search terms but I keep getting the following:

• Amplicons who have metagenomics in the title

• Metatranscriptomics that have metagenomics in the title
