How can I access PubMed's database using BigQuery

Question

When accessing google_patents_research.publications table from BigQuery I can filter results by the top_terms column. This column uses Google's machine learning algo to search the text inside a patent and extract the words it finds most meaningful. I was wondering if there is a similar search using BigQuery that can be done on PubMed's database. According to NCBI docs there is a dataset called nih-sra-datastore which should be accessible from BigQuery, but it doesn't show up when searching for it in BigQuery's console search box.
