# Search by Tags

> Find documents instantly using tags and content

## Overview

Search across your entire document library using tags—titles, dates, and text content. No more digging through folders.

## How It Works

When you upload a PDF, OkraPDF extracts and indexes:

* **Document metadata** — title, author, dates, page count
* **Full text** — every word in the document

All searchable from one place.
