Comment 15 for bug 1847976

OK, here we go:

I open a book, enter f.i. a words that can not be found.
I look in viewer-webengine.json and the word is there.
Then I search for a word that can be found.
If I look in viewer-webengine.json at that moment, with viewer stil open, I can see that only the last typed in word is there, the other one is gone.

Doing this the other way around, first a word that can be found, that appears in viewer-webengine.json.
Then a word that can not be found, that appears in viewer-webengine.json also.
Then the word that can be found again. If I look in viewer-webengine.json; the word that could not be found is gone.

Let change the last try, first a word that can be found, that appears in viewer-webengine.json.
Then a word that can not be found, that appears in viewer-webengine.json also.
But then the word that could not be found again: That erases the other word in viewer-webengine.json.

There are many more ways to test with words that can or can not be found, the outcom varies, but for sure word are lost.

Please fiddle around while checking viewer-webengine.json after every change, you wil see that building a list of search words like in viewer-3 is impossible.

Closing the viewer in between makes no difference, the changes in viewer-webengine.json are immediate.
