How to Override View

-- Normally you must not change FLEXIcontent core files, for consistency reasons plus they are overwritten when you upgrade FLEXIcontent.
-- But you can use a joomla template override for customizing any template file of FLEXIcontent view.

The template files of all FLEXIcontent view are
components/com_flexicontent/views/.../tmpl/default.php
components/com_flexicontent/views/.../tmpl/form.php
components/com_flexicontent/views/.../tmpl/special.php

To create a customization override view of it

1. copy above file to templates/mytemplate/html/com_flexicontent/myview/default.php 
2. modify it, to suit your needs

Now you can upgrade to newer FLEXIcontent versions without losing your customizations

tags view example:
components/com_flexicontent/views/tags/tmpl/default.php
copy to:
templates/mytemplate/html/com_flexicontent/tags/default.php 

search view example:
components/com_flexicontent/views/search/tmpl/default.php
components/com_flexicontent/views/search/tmpl/default_error.php
components/com_flexicontent/views/search/tmpl/default_form.php
components/com_flexicontent/views/search/tmpl/default_results.php
copy to:
templates/mytemplate/html/com_flexicontent/search/default.php
templates/mytemplate/html/com_flexicontent/search/default_error.php
templates/mytemplate/html/com_flexicontent/search/default_form.php
templates/mytemplate/html/com_flexicontent/search/default_results.php
