.. news! It seems the problem is a MacOS-Problem. If i use the OSX-Standard-Program Preview (in German Vorschau) theres a problem to save the with Lyx generated Files searchable. After the Compilation preview starts and the PDF-file in Preview is searchable. After saving the file with „Save As“ the saved file is not searchable.
If i use PDF Expert to show the lyx pdf-output and to save it, the pdf-file is searchable. Perhaps someone can use this Information. My Configuration: macOS Sierra Version 10.12.1 Preview (Vorschau) Version 9.0 ( 909.12)
