The part of a review that no tool can infer and every review must state: which databases were searched, with what query, on what date, and what limits were applied. PRISMA items 6 and 7 ask for it, and item 7 asks for the full strategy for at least one database so that it could be repeated.
Usage
gr_search(
databases,
dates = NULL,
limits = NULL,
registration = NA_character_,
other = NULL,
notes = NULL
)Arguments
- databases
Named character vector or list: name of each source, value the query string run against it. The query is the point; a review reporting "we searched PubMed" without it cannot be repeated.
- dates
When each search was run, as
YYYY-MM-DD. One value, or one per database. Searches drift: a review is a statement about a date.- limits
Limits applied: language, publication years, study design filters. Free text; a review states them whatever they were.
- registration
Registration identifier (a PROSPERO number, say), or
NAand say so. PRISMA item 24 asks either way.- other
Any further sources: reference lists checked, experts contacted, registers, preprint servers, hand-searched journals.
- notes
Anything else the methods section has to say.
Details
This function computes nothing. It exists so the answer travels with the run
instead of living in a lab notebook. It reaches gr_flow() and the audit
report, and it round-trips through gr_protocol_save() alongside the
criteria, so what was searched and what was eligible are one artifact.
