Search topics
The best way to search for topics is to use the search query parameter, which searches the display_name, description, and keyword fields. Example:
Search topics'
display_nameanddescriptionfor "artificial intelligence": https://api.openalex.org/topics?search=artificial intelligence

Search a specific field
You can also use search as a filter, allowing you to fine-tune the fields you're searching over. To do this, you append .search to the end of the property you are filtering for:
Get topics with "medical" in the
display_name: https://api.openalex.org/topics?filter=display_name.search:medical
The following fields can be searched as a filter within topics:
| Search filter | Field that is searched |
|---|---|
You can also use the filter default.search, which works the same as using the search parameter.
