Hello, 
I have a complex search form. 
For this reason, I should change the search query based on the form parameters (input form) 
because it is impossible build a only query. 
Is it possibile change the search query of a "Lists&Search Types", for example, using  the plugin  "Code Pack (5 plug-ins)" to use php code directly, or is there a another away? 
I've normaly used this plugin for "Form & Content Type" but I don't know if "beforestore" or "beforerender" are usefull also for change the query of "List&Search" before to search. 
Can you help me to understand what I have to study?
