### 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:

```
<script>
  (function() {
    var fess = document.createElement('script');

          schema:
            type: array
            items:
              type: string
            example: [label]
        - name: field
          in: query
          description: Field name to generate suggest words
          required: false
          style: form
          explode: true
          schema:
            type: array
            items:
              type: string
            example: [python]
