Other results at server, and other at localhost

I hav this problem, i have code script and at servers this himself code return others results for the result of the query in the text field, but only for the tramadol and lorazepam phrases, that is, as in this text box on the server there is a phrase tramadol and lorazepam that writes that no results were found and for the rest returns well, but for me on the server the same code works well. What is it going on here, do I have to show the code?
