What is the Relevance Threshold?

Think of this as a "strictness dial" for search results:

• Lower (0.5-1.0): Only show abstracts very closely related to your search
• Medium (1.0-1.5): Show moderately related abstracts (recommended)
• Higher (1.5-2.0): Cast a wider net, may include tangentially related abstracts

💡 Getting too few results? Try increasing the threshold. Results seem off-topic? Try decreasing it.
