No.
You could do something like this:
[[!pdoResources?
...
&includeTVs=`event-date`
&where=`[[!getWhere]]`
]]
Snippet getWhere:
<?php
$where = [];
//read search parameter
$search_string = $_GET['search'] ?? '';
//do some sanitizing
$search_string = $modx->sanitizeString($search_string);
$search_string = strip_tags($search_string);
$search_string = trim($search_string);
if (mb_strlen($search_string) > 2){ //check min search length
//filter by search term
$where[] = ["pagetitle:LIKE" => "%" . $search_string . "%", "OR:content:LIKE" => "%" . $search_string . "%" ];
}
//filter by event-date
$where[] = ["event-date:>" => date('Y-m-d H:i:s')];
return json_encode($where);
Depending on your use case, something like this might be a viable replacement for SimpleSearch and is probably easier to implement than a custom postHook.
