Fulltextsearch does not find first word of line in Word document

I just installed the new elasticsearch fulltext search and it seams to work, except it does not seam to find the first word of every line inside Word documents. But It does work with the second, third and so on. Is this a known problem?

It is a known issue

as well as PDF :frowning:

But not every line of the PDF, i could not find it out ATM.

Some are found, some not.
