This could be done pretty cheaply and would result in one of the most requested features being implemented, hence why set to 0.4 milestone.
To do:
If someone can prepare the list for the main search engines (yahoo, aol, etc.), this would help save us big time to make this feature in 0.4 :-)
(In [1158]) - on a rainy sunday night, implented one of the most requested feature which was little work and should make a lot of users happy!
fixes #747
adding links on both sub tables for search engines and keywords linking directly to the search engine page for this keyword
added definition for the main search engines (approx 15) users can contribute more if they like; if a definition, eg. "search?q={k}" for Google is not found, then we simply link to the search engine homepage.
updated FAQ on how to add a search engine see http://piwik.org/faq/general/#faq_39
added tests to check that the search engine file is defined properly
(In [1163]) refs #747 better display of queries with spaces
