NCBI has improved its search functionality in the “all databases” search to be compatible with natural language searching. In the past, natural language searching for sequence data brought up too many results or sometimes zero results. Now you can search NCBI more intuitively than before and receive good results for genes, nucleotides, and assemblies! How do you get started with NCBI’s new natural language searching?

Go to the homepage of NCBI. The default search shows “All Databases” in the drop-down box. Here you can try out some of the improved search queries:

Genes

• [Species name] + [gene symbol]
  • Chelonia mydas SDHA

• Rat B2M

 

Nucleotide Sequences

• [Species name] + [gene symbol] + mRNA/transcript/CDS
  • Salmo salar SUMO1 mRNA

• Mus musculus Abcg2 transcript

• Cow CA2 CDS

 

Genome Assemblies

• [Assembly name]
  • GRCz11

• [species name] + assembly/genome
  • Chicken assembly

• Escherichia coli genome
