Scopus Search String Builder

Scopus Advanced document search accepts fielded expressions such as TITLE-ABS-KEY. This scope searches titles, abstracts and keywords; it is broader in metadata coverage than PubMed title/abstract fields. The builder wraps each concept’s alternatives in that scope, so the hypertension-and-exercise example becomes two TITLE-ABS-KEY blocks connected by AND. Alternative terms stay inside their own OR group. Explicit grouping makes the intended logic reviewable when additional proximity clauses or exclusions are introduced.

Scopus does not provide MeSH heading explosion. A biomedical concept strategy may still contain NLM-verified MeSH candidates for the PubMed adaptation, but the Scopus compiler omits those controlled-vocabulary clauses and says so. Do not paste [mh], an Ovid exp heading or an Emtree /exp expression into this query. If a heading label is also useful author terminology, it must be included deliberately as a free-text synonym. Its presence in a controlled vocabulary does not guarantee that Scopus authors or keyword fields use the same wording.

PICO can help organize a clinical question, yet a Scopus strategy should be shaped by searchable concepts. Population and intervention/exposure usually provide a starting point. A comparator may be mentioned only in the full text, while an outcome can have many measurement-specific names. This tool may therefore leave supplied comparison or outcome details outside mandatory AND groups. Review that decision against your screening criteria and known papers. The aim is a useful candidate search, not automatic conversion of every sentence in the question into a constraint.

Treat the generated strategy as an AI-assisted draft for reviewer confirmation. A well-formed Boolean expression can still miss a field’s preferred terminology, retrieve the wrong meaning of an abbreviation, or make an unnecessary outcome mandatory. Start with a small set of known relevant papers. Check whether each paper would be retrieved by the population and intervention blocks separately, then by the combined strategy. If a paper is missed, inspect its title, abstract and indexing to find the cause before adding more synonyms. More terms are useful only when they represent the intended concept.

Keep eligibility criteria separate from search constraints. A language restriction, human-study filter or study-design filter can remove recent or incompletely indexed records. Apply only justified limits using the destination interface controls, and record exactly what you selected. The saved concept strategy can carry structured limits and exclusions, but unsupported settings appear as adaptation notes and are not silently applied. Excluding records with NOT deserves particular care: a relevant study can mention the excluded population or treatment in its background.

Copy or download the edited query after testing it. Keep a search log alongside the plain-text export with the database and host, coverage segment, vocabulary release where available, date and time, exact executed string, selected filters, result count and platform warnings. The generated text alone is not a complete reproducibility record. Session storage keeps this tab’s draft and interface edits, but it is not a permanent project archive. Ask a librarian or information specialist to review a consequential review search before final execution; this tool does not certify recall, precision or methodological adequacy.
