i noticed some weird search results being recorded like this:

the search function should only be recording a result if it finds a result, so this should not be added unless it can actually find this text, which i doubt it. 

Some annoying robot is adding this i think. 

page: search.page.php

PHP

if($search_value > "") {
    $page_content .= $class->list_all(
        $start = $start_val,
        $max = $page_step,
        "search", 
        $template_file_name,
        $search_term = $search_value
    );
}

i think the issue is with the search link text being added from the url. it does not validate if the text exists on the page before adding it, so need a check on there before adding it. 

e.g: https://kruxor.com/view/code/DPkzR/weird-search-results-being-recorded/search_text:::weird%20search%20results%20being%20recorded 

I have only allowed the characters on searches, so this should fix the random text issues now.

PHP

$search_text = preg_replace("/[^A-Za-z0-9 ]/", '', $search_text);

see if this solves the problem
