Hi guys, below is default OSCommerce complete search file, the file name is advanced_search_result.php

oscommerce is very free famous script, but..

ironically this file is searching all words that typed by user, even just a single word like "A" or "An"
it is searching in mysql, so its make [COLOR="Red"]very very high load for the server[/COLOR], imagine its need to search for all words that contain "A", how if you have 100.000 products/items in your site :rolleyes:


maybe the best option to reduce the load server is to set the minimum character to search, example to search only minimum 4 or more character, there is no setting for doing this in oscommerce setting, so its need to change some code in a file, i had asking this in oscommerce forum, but they cant do this http://forums.oscommerce.com/index.php?showtopic=340368




i think the part need to edit is in bold below, please help guys to make it only search 4 or more character words






here is advanced_search_result.php file content :
