I'm trying to search a file for all occurrences of PgfTag or FSize, using PgfTag|FSize – unsuccessfully. Notepad++ 5.8.5: any suggestions for OR searches in this version welcome!
Error running search query: [Errno 111] Connection refused – so my apologies if there is already an answer to this question
You should use a newer version of Notepad++, with the new regex engine. The old engine does not support OR.
You're right <g> running 6.5 off a USB stick to get round obsolete corporate installation … works like a charm!
