[tw5] Search in field

Hello,

<$keyboard key=“escape” actions=’<$action-setfield $tiddler="$:/temp/demo/qa/search-details" $field=“text” $value=""/>’>
<$edit-text tiddler="$:/temp/demo/qa/search-details" filed=title tag=input default="" placeholder=“Search” class=“alert alert-info w-100”/>
</$keyboard>

<$list filter="[!is[system]search:text[{{]search:title[,]search:title{$:/temp/demo/qa/search-details}]" variable=tagname>

<$checkbox tag=<> tiddler=<> ></$checkbox>↑ <>
</$list>

Works perfect!
But how do I modify this code so that I can search in field X of Tiddler XX?
And how do I display the values from that field as a link?

List as link:

<$link to=<> />
