使用PDF创建索引。

Answer 1

我认为你可以使用pyPdf Python库（http://pybrary.net/pyPdf/）。 此代码显示包含所需单词的页数：

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

同样但使用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
