index for all file words

hi all
i have book that i want to make an index for it.
i am using the normal way which to mark the words one by one and after all i set the index at the end of last page.

my question has two parts:
first : is there any way to mark all the words of file without repeat and make the index for them all ?
second: how to put the number of frequency for every word at the end of it's line ?

hope to be cleared ,and most to find help from kind people like you

kind regards
sherif
