Module query 

Query builder for constructing PubMed search queries with filters

This module provides a flexible query builder for constructing complex PubMed search queries using E-utilities syntax. The query builder supports:

• Field-specific searches (title, abstract, journal, etc.)
• Date filtering with flexible precision
• MeSH term filtering
• Author and affiliation filtering
• Boolean logic operations (AND, OR, NOT)
• Article type and language filtering
• Query validation and optimization

Examples

Basic search:

use pubmed_client::pubmed::SearchQuery;

let query = SearchQuery::new()
    .query("covid-19 treatment")
    .published_after(2020)
    .free_full_text_only()
    .limit(10);

Complex boolean search:

use pubmed_client::pubmed::{SearchQuery, ArticleType, Language};

let ai_query = SearchQuery::new()
    .title_contains("machine learning")
    .or(SearchQuery::new().mesh_term("Artificial Intelligence"));

let medical_query = SearchQuery::new()
    .mesh_term("Medicine")
    .and(SearchQuery::new().human_studies_only());

let final_query = ai_query
    .and(medical_query)
    .article_type(ArticleType::Review)
    .language(Language::English)
    .published_between(2020, Some(2023));
