To get the search to pick up product codes (sku's) in my 4.0.13 store where I do not use the full description field, I did a search and replace with my text editor in the following files:

search.php
include/search.php
skin1/customer/search.tpl

I replaced "fulldescr" with "productcode". This seems to work great for picking up the product code.

To get the s's stripped from the search term, I revised funkydunk's original code a bit.

In the 4.0.13 include/search.php file,

I replaced this

$data["substring"] = trim($data["substring"]);

with this

$data["substring"] = trim($data["substring"]);
   // code to strip last s from search string 
   $start = (strlen($data["substring"])-1); 
   // echo $start; 
   // echo "
"; 
   if ((substr($data["substring"],$start,1)=="s")||(substr($data["substring"],$start,1)=="S")){ 
   $data["substring"] = substr($data["substring"],0,$start); 
   // echo $substring; 
   } 
   // end of code to strip last s from search string

This seems to work fine.

Hope this helps.
