Good morning to all,
jafeth here is what I have just tested and works
In components\com_cckjseblod\views\search\tmpl\search.php at row#73 you will find an if clause that checks whether there was a result or not present.
What you need to do is down at row #125 load an optional template as follows
1. put the following code as an else clause to existing if clause
else {
echo $this->loadTemplate('noresults');
}
2. create a file in the same folder mentioned above called search_noresults.php and put in place the content you want to convey to your users when no result is present
and this should do it.
Note: when upgrading you might loose this adjustments and therefore are to be considered as a hack but will definitely do what you asked for.
Further it works in both content and list templates cases.
Edit: forgot to mention at last but not least, there is forum posting
rules here that we all should try to follow.
Good luck!
Thanks to you.!!"
