[TYPO3] built-in search module

[Piotr B.]

hi!

i'm configuring a searchmodule, built-in typo3 [no search extensions 
installed].

the search-box is in the left column of my page [narrow column]. 
everything works, looks good until i'm trying to search something.. i 
can't find how to change this "bugs":
- search opens a new browser window [how can i target to "_self"?]
- search results are inserted into my narrow - left column [how can i 
insert them into main column? any marks to enter?]

maybe some links to read about it?
typo3 doc didn't help me.. or maybe i can't define what to look for..

greetz and tia!
