[support] Custom Advanced Search

[Fred Jones]

I am trying to create a custom search, i.e. one which will only search 
in certain CCK fields. I believe that hook_search for Drupal 5 is what I 
need:

http://api.drupal.org/api/function/hook_search/5

but when I set this up in my custom module and run a search $op comes 
through as 'name' but not as 'search'.

Yet I am seeing the search results page. Is this expected behavior? If 
so, can someone explain to me what I am missing because I was expecting 
$op to be 'search' so I could add my keyword pairs to the search SQL to 
limit it. Or perhaps this is indeed not the correct approach?

Thanks,
Fred
