Create an index out of a PDF.

I think you can use pypdf Python library for this. This code show numbers of pages which include required word:

from pyPdf import PdfFileReader

input = PdfFileReader(file("YourPDFFile.pdf", "rb"))

numberOfPages = input.getNumPages()

i = 1
while i <  numberOfPages:
    oPage = input.getPage(i)
    text = oPage.extractText()
    text.encode('utf8', 'ignore')
    if text.find('What are you looking for') != -1:
        print i
    i += 1

The same but working with Python 3

from pyPdf import PdfFileReader

input = PdfFileReader(open("YourPDFFile.pdf", "rb"))

numberOfPages = input.getNumPages()

i = 1
while i <  numberOfPages:
    oPage = input.getPage(i)
    text = oPage.extractText()
    text.encode('utf8', 'ignore')
    if text.find('What are you looking for') != -1:
        print(i)
    i += 1
