Struct FindWorksParams 

pub struct FindWorksParams {
    pub query: String,
    pub count: Option<u32>,
    pub filter: Option<String>,
}

Parameters for semantic search (/find/works). Uses AI embeddings to find conceptually similar works. Requires an API key. Costs 1,000 credits per request.

use papers_openalex::FindWorksParams;

let params = FindWorksParams::builder()
    .query("machine learning for drug discovery")
    .count(10)
    .filter("publication_year:>2020")
    .build();

Fields

query: String

Text to find similar works for. Can be a title, abstract, or research question. Maximum 10,000 characters. For POST requests, this is sent in the JSON body as {"query": "..."}.

count: Option<u32>

Number of results to return (1-100, default 25). Results are ranked by similarity score.

filter: Option<String>

Filter expression to constrain results (same syntax as list endpoints). Applied after semantic ranking.
