Drupal default search OR instead of AND

Question

Is it possible to manipulate the full search term of Drupals default search engine? I want to make it an OR query without the user noticing it.

For example, if the user searches for

bread butter

it should be changed into

bread OR butter

right before passing it to the search_data() function. It know the hook_search_preprocess(), but hat function processes one word at the time.

Answer 1

You could either use the Advanced Search module or use Google Custom Search. The Google Custom Seach or the Google Site Search module would be able to provide it, but you could choose for the manual integration too.
