vbcode / search.php

I'm finalizing a vbCode for a search function on our board, and was wondering how I could emulate an advanced search without using search.php's HTTP_POST function.

I know for simplesearches one could use this:

https://vborg.vbsupport.ru/search.ph...ortby=lastpost
&sortorder=descending&beforeafter=after&action=simplesearch&query={option}

(linebreak intented to prevent f**king up the page)
But how can I get this to work with 'hello AND *bullet* NOT *bulletin' ? (sample query ofcourse)

The vBcode will be like this:

[searchthis={option}]Search for this: {param}[/searchthis]

Output:
Search for this: vbullet*

This is being used at our board to help people better understand and use the search function.

Thanks for looking into it!
