[wp-hackers] Custom search form on wordpress as CMS

[mailapera]

Hello,
 Do you know a way to enable wordpress to use complex search forms? I need
combo boxes (drop down), and check boxes only in this form. How would I pass
all the variables to the algorithm and store the data in the DB? It seems
the only search possible is the in site google kind of search, with one open
text field only. I have seasrched the web extensively but could not find
anything.
