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

[Fess Site Search](https://github.com/codelibs/fess-site-search) provides [scripts](https://fss-generator.codelibs.org/docs/manual) (see below) to help you migrate from GSS/CSE.
Using the, you can replace existing GSS/CSE JavaScript codes with:

```
