We convert the pdf file which is created in Arabic, when we convert the pdf file we strip out all of the words on the pdf file page and copy them into a text file.
If I copy a word from the text or word file and use our search feature the word is found.
However, if you type the same word in Arabic in the search feature then the search feature can not find it.
Our same process works for Example, Spanish, English, French and Hebrew.
I am attaching an example of a pdf file and the words in the text file.
