Also i don't know if this was your problem. But when you launch a node, the type parameter is the name of the executable to launch. Therefore since python does not need a compiler, and the executable is the own .py file. You need to just specify the .py file. This means something like this.

<node name="search" pkg="searching_tobot" type="**search.py**" output="screen">

I had a similar problem and this worked for me.

Hope this helps to anyone!
