## What You Get

* **Full-text search** - Search across abstracts and paper content, not just titles
* **Author metadata** - Author names, affiliations, and ORCID IDs
* **Citation data** - DOIs, citation counts, and reference links
* **Publication dates** - Filter by date ranges for time-sensitive research
* **Semantic ranking** - Results ranked by relevance to your query

## Quick Start

<CodeGroup>
  ```python Python theme={null}
  from valyu import Valyu

  valyu = Valyu()

  response = valyu.search(
      "CRISPR gene editing therapeutic applications",
      search_type="proprietary",
      included_sources=["valyu/valyu-pubmed"],
      max_num_results=10
  )

  for result in response.results:
      print(f"Title: {result.title}")
      print(f"Authors: {', '.join(result.authors) if result.authors else 'N/A'}")
      print(f"DOI: {result.doi or 'N/A'}")
      print(f"Content: {result.content[:300]}...")
  ```

  ```javascript JavaScript theme={null}
  import { Valyu } from "valyu-js";

  const valyu = new Valyu();

  const response = await valyu.search(
    "CRISPR gene editing therapeutic applications",
    {
      searchType: "proprietary",
      includedSources: ["valyu/valyu-pubmed"],
      maxNumResults: 10
    }
  );

  response.results.forEach((result) => {
    console.log(`Title: ${result.title}`);
    console.log(`Authors: ${result.authors?.join(", ") || "N/A"}`);
    console.log(`DOI: ${result.doi || "N/A"}`);
    console.log(`Content: ${result.content.slice(0, 300)}...`);
  });
  ```
</CodeGroup>

## Use Cases

* **Literature reviews** - Comprehensive searches across biomedical literature
* **Drug discovery research** - Find studies on compounds, targets, and mechanisms
* **Clinical evidence** - Locate clinical studies and treatment outcomes
* **Systematic reviews** - Gather sources for meta-analyses
* **Medical AI training** - Build datasets for healthcare AI applications

## Combine with Other Sources

PubMed works well combined with other healthcare datasets:

```python theme={null}
response = valyu.search(
    "CAR-T cell therapy clinical outcomes",
    search_type="proprietary",
    included_sources=[
        "valyu/valyu-pubmed",
        "valyu/valyu-clinical-trials",
        "valyu/valyu-biorxiv"
    ],
    max_num_results=20
)
```
