### Google Site Search (GSS) / Google Custom Search (GSE)

[Fess Site Search](https://github.com/codelibs/fess-site-search) provides a drop-in replacement for GSS/CSE JavaScript.

#### Migration Steps

**Step 1: Set Up Fess Crawling**

1. In Fess Admin, create a new Web crawling configuration
2. Add your website URL as the starting point
