Screen or filter reports based on a query

The Screener class filters PFD reports according to a plain‑English query. This class lets you submit a user-query (e.g. "Deaths in police custody") and have the model screen thousands of reports for possible matches.

The following pages cover how to use it:

• Getting started – run your first screen and understand why an LLM beats simple keyword search.
• Additional options – annotate instead of filtering and control which columns are read.
• Tips for writing a good user query – craft prompts that get accurate results.
