Unfortunately, this is only possible out of the box if the user writes in the 
search field :
  $:Fruit=Apple


It is quite complex to do it from a dedicated search box, and you should know 
some PHP and about PmWiki Forms. 

In config.php, you can intercept the PTV search string and append it to the 
regular search string which is "q", something like:

  foreach ($_REQUEST as $key=>$value) {
    if (substr($key, 0, 4)=='ptv_' && $value>'') {
      $_REQUEST['q'] .= " $:".substr($key, 4)."=\"$value\"" ;
    }
  }

In the search form, instead of or in addition to the input field named "q", 
you need to have a field named ptv_Fruit. 

So, in a default HTML form in the skin template, you replace 
  <input type='text' name='q' /> with
  <input type='text' name='ptv_Fruit' />

Or, if you have a search form in a wiki page, 
(:input form action={*$PageUrl} method=get:)
(:input hidden n {*$FullName}:) (:comment this line may be optional:)
(:input hidden action search:)
(:input text $:Fruit:) (:input submit value="Search":)
(:input end:)
(:searchresults:)

Here, instead of (:input text q:) we have (:input text $:Fruit:).
