Running systematic-review search passes that need repeatable search strings. Using NCBI E-utilities directly from Python, shell, or another HTTP client. Start with the research question, split it into concepts, then combine concepts with Boolean operators. Useful PubMed field tags: [ti]: title [ab]: abstract [tiab]: title or abstract [au]: author [ta]: journal title abbreviation [mh]: MeSH term [majr]: major MeSH topic [pt]: publication type [dp]: date of publication [la]: language Examples: Prefer MeSH when the concept has a stable controlled-vocabulary term. Combine MeSH with title/abstract terms when the topic is new or terminology varies. Correct subheading syntax puts the subheading before the field tag: Use [majr] only when the topic must be central to the paper. It can improve precision but may miss relevant work.
