SRAdb: Search full text in study_type

Question

[rororo]

I want to search the entire SRA using the SRAdb package. Specifically, I want to get all accession number of Metagenomes (as study_type) with "enrichment culture" (full text search) The SRAdb manual unfortunately only shows either how to display all study_types or the full text search.

Have you considered using NCBI eutils?

NCBI does not mention SRA
