Need Search index. Search is slow in 1000+ pages.
Searching for a word in ebooks with 1000+ pages is too slow. A search index needs to be maintained in the device cache.

Why did I receive this notification.....embedded index works quit well.
@Sadeq Ebrahimi : Try copying the content from the pdf to the search box and see if it works. Sometimes, there are two spaces between the words and can be easily ignored.

also some time search dose not work. for instance I search "Proof of Theorem 1.2" in a document but the result say that "no matches found " since I just copied that word or sentence
