I agree.

It takes quite a bit of time to become "comfortable" with finding the one specific bit of information that you need from this site.

Generally, seeking it out via perusing threads is not going to be successful.

Additionally, the search function is extremely limited in it's capabilites because of the fact that it can only search individual words. If you're looking for "vacuum modulator", you'll get very single post that has the word "vacuum" or the word "modulator". It makes for quite a bit of work to find what you need.

Google, however, is the anwer to your dilemma. You can search a specific phrase, such as "vacuum modulator" and you'll get all the posts that contain both words. You can restrict the domain to "Mercedesshop.com". I use Google exclusively as the search engine and it shortens the time dramatically.
