Yes.
In this document which explains the program flow of Zen Cart, you'll see that the header_php.php file processes code "before" the "header" is generated. It does all the background processing before anything is sent to the browser (except perhaps a "headers already sent" or other error-related messages), including the <HTML> and <HEAD> tags.
Program-Flow document:
http://www.zen-cart.com/index.php?ma...roducts_id=378
However, with that said, from what you've posted earlier, when you're inserting your "include" statements for those files, you're somehow getting an error message (the variable not found message) which suggests that somehow the normal flow of the Zen Cart page-loading activity has been intercepted and pieces of it skipped. I'm not sure exactly why.
Where exactly in the header_php.php file did you put the includes? Without studying it in great detail thus far, I would start by suggesting putting them at the end, before the closing ?> tag.

Re: Integrating 3rd party search engine
The error messages that were being generated were ZC errors made visible by this line of code in the search engine:
error_reporting(E_ALL);
I commented out that line and all works well.
I'm happy - thanks for your help!
