# CLAUDE.md - Fess Crawler Development Guide

Quick reference for AI assistants working on the Fess Crawler project.

## Project Overview

**Fess Crawler** is a Java-based web crawling framework for enterprise content extraction.

### Essential Info

- **Language**: Java 21+
- **Build**: Maven 3.x
- **License**: Apache 2.0
- **DI**: LastaFlute DI
- **Repo**: https://github.com/codelibs/fess-crawler

### Tech Stack

         * According to RFC 9309:
         * 1. Find the longest matching pattern (by priority length)
         * 2. If both Allow and Disallow patterns match with the same length, Allow takes precedence
         * 3. If no pattern matches, the path is allowed by default
         *
         * @param path the path to check
         * @return true if the path is allowed, false otherwise
         */
