Search concepts
These are the original OpenAlex Concepts, which are being deprecated in favor of Topics. We will continue to provide these Concepts for Works, but we will not be actively maintaining, updating, or providing support for these concepts. Unless you have a good reason to be relying on them, we encourage you to look into Topics instead.
The best way to search for concepts is to use the search
query parameter, which searches the display_name
and description
fields. Example:
Search concepts'
display_name
anddescription
for "artificial intelligence": https://api.openalex.org/concepts?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 concepts with "medical" in the
display_name
: https://api.openalex.org/concepts?filter=display_name.search:medical
The following field can be searched as a filter within concepts:
You can also use the filter default.search
, which works the same as using the search
parameter.
Autocomplete concepts
You can autocomplete concepts to create a very fast type-ahead style search function:
Autocomplete concepts with "comp" in the
display_name
: https://api.openalex.org/autocomplete/concepts?q=comp
This returns a list of concepts with the description set as the hint:
