NCBIGene Search

Search the NCBI Gene database using the E-utilities API. Find gene IDs (Entrez Gene IDs) by gene symbol, name, or keyword combined with an organism filter. Returns a list of matching Gene IDs that can be used with NCBIGene_get_summary. Essential for resolving gene names to standardized NCBI Gene IDs. Example: searching 'TP53' in Homo sapiens returns Gene ID 7157; 'BRCA1' returns 672.
