How does Laravel turn this code into a link? - laravel

Question

Consider this block of code from a Laravel blade file:
<div class="result-content">
<h6>{{ $item->name }}</h6>
<div>{!! Str::limit($item->desccription, 120) !!}</div>
#if($item->type == 'lot')
<div>{{ $item->info ? "Current Bid: $".number_format($item->info, 2) : 'No bids yet' }}</div>
<div>{{ \Carbon\Carbon::parse($item->start)->setTimezone($_COOKIE['timezone'])->format('n/j/y g:ia T') }} - {{ \Carbon\Carbon::parse($item->end)->setTimezone($_COOKIE['timezone'])->format('n/j/y g:ia T') }}</div>
#else
<div>{{ $item->info }} Lot{{ $item->info > 1 ? "s" : '' }}</div>
<div>{{ \Carbon\Carbon::parse($item->start)->setTimezone($_COOKIE['timezone'])->format('n/j/y T') }} - {{ \Carbon\Carbon::parse($item->end)->setTimezone($_COOKIE['timezone'])->format('n/j/y T') }}</div>
#endif
<a href="{{ $item->search_url }}" title="">
View: {{ $item->search_title }}
</a>
</div>
Somehow or other, this renders in a browser as a block of text that is all included in a link tag, and "$item->search_url" becomes the link url. But the link is wrong - it just points back to the page this text is appearing on. I need to figure out where "search-url" is assigned its value, so I can fix it. But I am entirely new to Laravel, and I can't figure out where or how "search-url" is getting assigned a value. I've searched the entire system with Visual Code, and that name doesn't appear anywhere else. It's not a variable, it's not a property name, it's not a database field name.
Where is that variable getting assigned?
