'Only Introtext' is not among Custom Properties set of views.
However it is fairly straightforward to modify the Custom Properties layout to meet that requirement. The recommended path is to make a template override, so that future updates of Custom Proerties won't overwrite your customization.
- create directory
com_customproperties/search for the overridden Custom Properties layout in
templates/<your template>/html/
- copy the original CP file
components/com_customproperties/views/search/tmpl/default_item.php to
templates/<your template>/html/com_customproperties/search
- edit
templates/<your template>/html/com_customproperties/search/default_item.php:
- delete or comment lines 15-17
Code:
<dt class="cp-title result-title">
<a href="<?php echo JRoute::_($this->row->href);?>"><?php echo $this->escape($this->row->title);?></a>
</dt>
