Make them searchable

Files aren't searched directly — records are. Each record points at one file, and Search Stack reads that file's text into the record.

A record per file

Create a list — docs — with one record per file. Each record carries a document field holding the file's address, plus whatever you want to show with a result: a title, the authors, a category.

Text is extracted automatically as each record lands. Nothing to configure, nothing to run.
Attach an embedding model too if you want search by meaning on top of the extracted text.

The docs list in the console: one record per paper, each with a document_url pointing at the PDF, plus title, authors, category and year

Or from code

One request — the document field's address is all extraction needs:

POST https://api.searchstack.dev/search-result/Demo/docs/with-fields
X-API-Key: {your key}
Content-Type: application/json

[
  {
    "name": "paper-attention",
    "title": "Attention Is All You Need",
    "authors": "Vaswani et al.",
    "document_url": "https://.../papers/paper-attention.pdf"
  }
]
