Preview search error on 10.15.7
I used to use Acrobat Pro 8 when combining pdfs but it no longer works after upgrading to Catalina. So, I've used Preview to combine two fully searchable pdfs that contain text only. However, when I open the newly combined pdf and use the search window to find results for a particular word, for some reason it only gives me the uppercase results. And if I'm searching for a word that only appears in lowercase in the pdf, the search doesn't show any results at all. I've tried closing and reopening Preview, quitting and reopening and also restarting computer. Has anyone experienced and resolved this issue? Or can you recommend a free app that allows me to combine pdfs. Many thanks.
