Search Strategy Guide: Physics & Astronomy
A rigorous, reproducible search query is the cornerstone of any systematic review search strategy or scoping review. In the field of Physics & Astronomy, where literature spans multiple indexing networks, constructing a validated query string ensures comprehensive retrieval and minimizes bias. This guide outlines how to optimize your queries inside arXiv, INSPEC & Web of Science and related databases utilizing Physical Phenomena entities.
1. Structured Search Design & Boolean String Construction
To achieve maximum query sensitivity for Physics & Astronomy studies, literature searches must deploy optimized boolean search operators in structured sequences within arXiv, INSPEC & Web of Science. A rigorous boolean operators search links overlapping themes using logical OR statements, while narrowing the overall scope with AND operators. Advanced truncation research methodologies recommend truncating word roots (such as `analy*` or `therapy*`) to capture diverse morphology variations, thereby optimizing total citation retrieval.
2. Controlled Vocabularies & Subject Headings
Engineering and computer science literature syntheses in Physics & Astronomy rely on highly precise queries across platforms like IEEE Xplore, ACM Digital Library, or Scopus. Investigators must practice strict database query optimization to bypass interface limitations in arXiv, INSPEC & Web of Science and ensure that the query matches indexing structures precisely. This includes managing nesting limits, field restrictions, and indexing properties unique to Physical Phenomena computational archives.
Before executing the query in arXiv, INSPEC & Web of Science, researchers in Physics & Astronomy should structure their concepts using the PICO search strategy (Patient, Intervention, Comparison, Outcome) or SPIDER framework. This provides a blueprint for a systematic review search strategy or a scoping review search strategy matching Physical Phenomena fields. For audit purposes, it is standard practice to publish a systematic review search strategy table detailing the exact queries, date of execution, and total results retrieved from each database.
Sensitivity testing of a search string for Physics & Astronomy is performed by running the query against a validation set of known, highly relevant papers in arXiv, INSPEC & Web of Science. This validation step is a critical phase of the research stages process to ensure query coverage. Depending on the different types of research designs selected—whether it is a mixed methods research design, a longitudinal research design, or a study based on causal research—the search string must undergo multiple rounds of iterative refinement to maximize precision.

A rigorous systematic review protocol requires validating your search query against a pre-defined set of key baseline publications. The following three highly-cited papers indexed in OpenAlex are verified within the domain of Physics & Astronomy. Ensure that your final constructed query string successfully retrieves these references when executed inside arXiv, INSPEC & Web of Science.

4. Translating Queries Across Platforms
A search strategy developed for one database must be carefully translated before execution in another. For example, field tags in PubMed (such as [Mesh] or [tw]) will cause syntax errors if pasted directly into Scopus or Web of Science. Use the comparison table below to guide your translation process:
| Feature | PubMed / MEDLINE Syntax | Scopus Syntax | Web of Science Syntax |
|---|---|---|---|
| Controlled Vocabulary | "Term"[Mesh] | INDEXTERM("Term") | N/A (Uses Topic search) |
| Title / Abstract Search | term[tiab] | TITLE-ABS-KEY(term) | TS=(term) |
| Truncation Wildcard | * (replaces word end) | * (any characters) | * (replaces characters) |

PRISMA Compliance
The PRISMA 2020 declaration mandates that authors must present full electronic search strategies for all databases searched, including any filters used. This level of transparency is essential for the peer-review and validation process.
