Bug: Formatted Search uses title but should use name for formfield parameter

documenation for FormattedSearch says $formfield(name) but actually uses $formfield(title). Should use the meta field name.

Test case

The documentation for FormattedSearch is a bit inaccurate for $formfield(name). In fact the code picks up $formfield(title). This can be a problem if the title is not a WikiWord. For example, in the case I was working on, I find the following META tags at the bottom of the topic file:

META:FIELD{name="BuyerType" title="BuyerType" value="ComputerHardwareMfg, TeleCom"}%
META:FIELD{name="Region" title="[[Region]]" value="NorthAmericaRegion"}%
META:FIELD{name="CompanyRevenue2002MilUS" title="Company Revenue 2002 (Mil US$)" value="18915"}%
META:FIELD{name="CompanyRevenue2001MilUS" title="Company Revenue 2001 (Mil US$)" value="21790"}%

This works (clumsily) for something like


But blows everything up if you use the more complex

$formfield(Company Revenue 2002 (Mil US$))

I think it would be better to use the "name" field above, so that the documentation is correct. It is probably generally improper to use the title of the META field for processing. To fix this, make the following minor change in Search.pm:

sub getMetaFormField
        $title = $field->{"title"};          # should change to $title = $field->{"name"};
        $value = $field->{"value"};
        $value =~ s/^\s*(.*?)\s*$/$1/go;
        if( $title eq $name ) {
            $value = breakName( $value, $break );
            return $value;

Fix record

You are right about the usefulness of name vs title. I could not simply change from title to name because this would break existing applications that assume title. So I fixed it to look for name and title, this makes it behave the way users expect, and also should not break existing apps.
