[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');
    fess.type = 'text/javascript';
    fess.async = true;

${packaging.scripts.header}

#
# This script is executed in the post-installation phase
#
#   On Debian,
#       $1=configure : is set to 'configure' and if $2 is set, it is an upgrade
#
#   On RedHat,
#       $1=0         : indicates a removal
#       $1=1         : indicates an upgrade



# Sets the default values for fess variables used in this script
FESS_USER="${packaging.fess.user}"
FESS_GROUP="${packaging.fess.group}"
