spotlight search
I experience the following problem: I have a huge number of documents in txt format and in the Greek language, created in the past several years in windows ( various versions from 1998 till present, Windows 10). I use spotlight to search within them but spotlight does not recognise automatically their font so it does not search them. I have to convert each and every one of them to a recognisable by the spotlight font and save it, in order spotlight to perform searching by content. Of course I cannot do this as the number of them is huge, actually more than 80,000. How can I solve this problem please? I use a MacBook Pro and Mac OS high Sierra. Thank you.
MacBook Air, iOS 10.3.3
