what s the diference between search in the documentation that we access using Ctrl Alt F3 and Index in documentation that we access using Ctrl Alt F2

what type of help is available in each of them

Thanks

Search will look through the selected documentation for articles containing the words you search for (you can choose to only search titles if you want). Index is an alphabetical list of all of the topics, and so you can only find files based on the beginning of the titles. I personally don't use the index, but I have noticed that it seems like it is used by the designer when you press F1 to look up a class or method, since if it doesn't find the article it takes you to the index.
