Search Strategy Guide: Chemistry & Materials Science
To construct a truly reproducible literature synthesis in Chemistry & Materials Science, investigators must systematically map their search terms. With research outputs in this field scattered across various indexing directories, preparing a structured systematic review search strategy ensures complete query sensitivity. This handbook provides the tools required to formulate queries within Reaxys & CAS SciFinder systems using Chemical Actions and Uses metadata.
1. Structured Search Design & Boolean String Construction
To achieve maximum query sensitivity for Chemistry & Materials Science studies, literature searches must deploy optimized boolean search operators in structured sequences within Reaxys & CAS SciFinder. 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 Chemistry & Materials Science 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 Reaxys & CAS SciFinder and ensure that the query matches indexing structures precisely. This includes managing nesting limits, field restrictions, and indexing properties unique to Chemical Actions and Uses computational archives.
A high-quality literature synthesis in Chemistry & Materials Science is grounded in a pre-planned structural model. Researchers typically adopt the PICO search strategy (or the SPIDER framework for qualitative reviews) to map key search entities under Chemical Actions and Uses. This framework forms the basis of the systematic review search strategy or a tailored scoping review search strategy inside Reaxys & CAS SciFinder. Preparing a detailed systematic review search strategy table detailing the exact string and retrieval yields is a fundamental reproducibility requirement.
Sensitivity testing of a search string for Chemistry & Materials Science is performed by running the query against a validation set of known, highly relevant papers in Reaxys & CAS SciFinder. 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.
Sample Search String Template for Chemistry & Materials Science
("Chemistry & Materials Science"[MeSH Terms] OR "chemistry & materials science"[All Fields]) AND
("Reproducibility"[MeSH Terms] OR "reproducibility"[All Fields] OR "repeatability"[All Fields]) AND
("Methods"[MeSH Terms] OR "methodology"[All Fields] OR "standards"[All Fields])Note: Designed for execution in Reaxys & CAS SciFinder. Truncation and field tags can be adjusted depending on the database's specific syntax.3. Search Strategy Validation Set (High-Impact Baseline)
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 Chemistry & Materials Science. Ensure that your final constructed query string successfully retrieves these references when executed inside Reaxys & CAS SciFinder.

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.
