Basics about aiSobiSearch

I appologize for my ignorence but I'm trying in hours to understand how this plugin works. I looked in forum and FAQs etc.... It is dump question for you but I have to ask: after I installed it (ver 1.0.10, joomla 1.5.14), I have this:
Warning: array_unshift() [function.array-unshift]: The first argument should be an array in /home/v/web/YqIF0LA30p4LsZY3beqMrOCoC1A7cB77/www.agsistemi.co.yu/plugins/search/aisobisearchitemsorder.php on line 26

How do I create table with search content and where I can put it. I suppose in SQL db, but how do I link it with sobi, and what should I put in sobi 2 clon arrea? Can you give me example of making this work (table, values in fields of plugin, result...) Once again I'm sorry for the stupid question. Thanks a lot, I will understand if you don't anwer me.
