# Keep only PDFs that mention a word

**Use case:** 

One row per PDF: the text, the page count, the title, the author and the dates the file carries, plus a hash of the text so you can tell when it changes. The keywords are matched against the text, the title, the subject and the author. Nothing extra is downloaded to apply them: the filter runs on the text that was already extracted.

## Input

```json
{
  "urls": [
    "https://www.irs.gov/pub/irs-pdf/fw9.pdf",
    "https://www.irs.gov/pub/irs-pdf/fw4.pdf",

## About this Actor

This example demonstrates how to use [PDF Text Extractor - Watch PDFs and Get Only What Changed](https://apify.com/neverempty/pdf-text-extractor-monitor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/neverempty/pdf-text-extractor-monitor.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
