Win Server 2019 file server, cannot find PDF's if windows search indexer enabled.

[#1]

Hello,

We have Windows Server 2019 Standard as file server (network share).

When turn on Windows Search indexing (it takes whole weekend to index) I cant find any PDF's when searching with pdf filename.

Even if I go with File Explorer to directory where this pdf is and do the search, it cannot find anything.

This doesn't happen with excel or word files.

If i take indexer off, every search takes really long time but it finds PDF's.

Today I did install Adobe PDF iFilter 9 for 64-bit platforms and also Adobe Acrobat Reader DC but i'll have to wait till friday to try again indexing.
