I find the following primitive behavior with Mathematica documentation center
1. In order to type new next in search field, I have to use command+A every time. Normally, in such software documentation, one should simply have to click or double click or use escape key
2. The search text cannot have any typos or human like text. For eg., if I ended up typing 'Forier' insted of 'Fourier', I get no results or for that matter 'how to execute a code?'
