Overton supports semantic searching of our policy documents. Semantic searching focuses on meaning rather than exact keyword matching.
How does it work?
Our semantic search is powered by our AI-generated document descriptions, which provide an overview of the document and the themes contained within it. Find out more about how we generate our document descriptions here.
The results of a semantic search will be documents that have a conceptual similarity to your search terms rather than just keyword matching.
Search syntax
In order to conduct a semantic search, you will need to prepend your search with “similar:”. For example, when conducting a search looking for documents that relate to the impacts of climate change on mental health, the search might look like:
similar: The document discusses the mental health impacts of climate change and provides guidance on how to maintain mental well-being during this challenging time. It highlights the various stressors associated with climate change, including extreme weather events, heatwaves, and droughts, which can lead to anxiety, depression, and post-traumatic stress disorder.
This will return results for policy documents where the AI document descriptions contain themes related to the mental health impacts of climate change.
