[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;

    0)
        STOP_REQUIRED=true
    ;;
    1)
        # Don't do anything on upgrade, because the preun script in redhat gets executed after the postinst (madness!)
    ;;

    *)
        echo "pre remove script called with unknown argument \`$1'" >&2
        exit 1
    ;;
esac

# Stops the service
if [ "$STOP_REQUIRED" = "true" ]; then

${packaging.scripts.header}

#
# This script is executed in the pre-installation phase
#
#   On Debian,
#       $1=install : indicates an new install
#       $1=upgrade : indicates an upgrade
#
#   On RedHat,
#       $1=1       : indicates an new install
#       $1=2       : indicates an upgrade



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

    ;;
    1)
        # If $1=1 this is an upgrade
        IS_UPGRADE=true
    ;;

    *)
        echo "post remove script called with unknown argument \`$1'" >&2
        exit 1
    ;;
esac

# Source the default env file

${packaging.scripts.header}

#
# This script is executed in the post-installation phase
#
#   On Debian,

#
#   On RedHat,
#       $1=0         : indicates a removal
