As a GREP newbie, I thought my searches rarely working was just me goofing. My experience is that I can make a search work if it does anything as long as it did not include looking for a plain word. Yet all the advice I get from books and forums is that I should be able to search for a word, say 'with', in a straightforward manner in either the grep or text tab of the Find.Change panel.
So after experimenting for awhile, I find my InDesign behaves like this.
Upon start up, if I search for a word (either by typing it or cutting and pasting it from the text) in the GREP find what line, it will be found.
As soon as I do a search in the text field, any further searches I try in GREP will not work if they include a plain word or a plain word in combination with any sort of pattern search. I just get a 'not found' message. Yet the word is in the text and the text search will find it.
And yes, I am searching on the entire document.
Am I doing something wrong? Any ideas?
