Step 3 - Build QueryParams

This tutorial covers how to build query parameters for API requests.

QueryParams Overview

QueryParams is used to configure API requests. It uses the builder pattern for easy configuration.

use ss_tools::QueryParams;

let mut params = QueryParams::default();
params
    .paper_id("abc123")
    .query_text("deep learning")
    .limit(10);

Paper Query Parameters

Basic Search

use ss_tools::QueryParams;
use ss_tools::structs::PaperField;

let mut params = QueryParams::default();
params
    .query_text("transformer architecture")
    .fields(vec![
        PaperField::Title,
        PaperField::Abstract,
        PaperField::Year,
    ])
    .limit(20);

Paper Details by ID

use ss_tools::QueryParams;
use ss_tools::structs::PaperField;

let mut params = QueryParams::default();
params
    .paper_id("204e3073870fae3d05bcbc2f6a8e263d9b72e776")
    .fields(vec![
        PaperField::Title,
        PaperField::CitationCount,
        PaperField::ReferenceCount,
    ]);

Filtering Papers

use ss_tools::QueryParams;
use ss_tools::structs::{PublicationTypes, FieldsOfStudy};

let mut params = QueryParams::default();
params
    .query_text("machine learning")
    .publication_types(vec![PublicationTypes::JournalArticle])
    .fields_of_study(vec![FieldsOfStudy::ComputerScience])
    .min_citation_count(100)
    .year("2020-2024")
    .open_access_pdf(true);

Author Query Parameters

Author Details by ID

For author APIs, the author ID is passed via the paper_id field.

use ss_tools::QueryParams;
use ss_tools::structs::AuthorField;

let mut params = QueryParams::default();
params
    .paper_id("1741101")  // author_id
    .author_fields(vec![
        AuthorField::Name,
        AuthorField::PaperCount,
        AuthorField::CitationCount,
        AuthorField::HIndex,
    ]);

Author Search by Name

use ss_tools::QueryParams;
use ss_tools::structs::AuthorField;

let mut params = QueryParams::default();
params
    .query_text("Yann LeCun")
    .author_fields(vec![
        AuthorField::Name,
        AuthorField::Affiliations,
        AuthorField::PaperCount,
    ]);

Author’s Papers

use ss_tools::QueryParams;
use ss_tools::structs::PaperField;

let mut params = QueryParams::default();
params
    .paper_id("1741101")  // author_id
    .fields(vec![
        PaperField::Title,
        PaperField::Year,
        PaperField::CitationCount,
    ])
    .limit(10)
    .offset(0);

Pagination Parameters

Use offset and limit for pagination:

use ss_tools::QueryParams;

let mut params = QueryParams::default();
params
    .query_text("neural network")
    .offset(0)    // Start from first result
    .limit(50);   // Get 50 results
