Certainly! To make your search query more comprehensive and targeted when looking for research articles about the relationship between sleep and weight control in the Web of Science, you can expand the keywords and use synonyms or related terms. This approach will help you capture more relevant articles that might use different terminologies. Here’s how you can structure an expanded search query:

Basic Concepts to Cover

1. Sleep: Includes terms related to sleep itself.
2. Weight Control: Encompasses terms related to weight management, including obesity, weight loss, and metabolic health.

Expanded Keywords

• For Sleep: sleep, insomnia, sleep quality, sleep duration, sleep deprivation, circadian rhythms.
• For Weight Control: weight control, weight management, weight loss, obesity, body weight, metabolic rate, fat loss, BMI (Body Mass Index).

Building the Search Query

Combine these terms using the appropriate Boolean operators (AND, OR) and consider using truncation symbols or wildcards if supported (* for multiple characters, ? for a single character within the Web of Science platform) to account for different word endings.

Example Query

Here is an example of how you could construct your search query:

(sleep OR insomnia OR "sleep quality" OR "sleep duration" OR "sleep deprivation" OR "circadian rhythms") AND ("weight control" OR "weight management" OR "weight loss" OR obesity OR "body weight" OR "metabolic rate" OR "fat loss" OR BMI)

Additional Tips

• Field Tags: If Web of Science supports field tagging (e.g., searching within titles, abstracts, keywords), use them to narrow your search. For example: TI=(sleep) AND AB=(obesity).
• Phrase Searching: Use quotes for phrases to ensure you are searching for the terms together as a phrase rather than individually.
• Subject Areas: Limit your search to relevant subject areas if the platform allows, such as medicine, psychology, nutrition, or public health.
• Review Articles: For a broader understanding or a summary of the field, you might specifically look for review articles by adding AND review.

Final Considerations

• Adjust Based on Results: Start with a broader search and narrow it down based on the quantity and relevance of the results you retrieve.
• Use Filters: Utilize Web of Science filters to refine your results by year, document type, language, etc., after you perform the initial search.

This expanded and structured approach should help you retrieve a more comprehensive set of relevant academic articles related to sleep and weight control.
