I am hoping to write a long(ish) article and was going to use \include thus enabling me to work on each section separately. When it comes to indexing I wondered if there was any way to globally search for and find terms to be included in the index or would I need to go through each section in turn. I have tried to do it through the generated PDF - search the PDF and then CMD click the word, it locates it but there seems no way to move to the next occurrence.
Sorry if the question is too basic, I just wanted to make sure before I start.
After more research I suspect the answer is here: https://tex.stackexchange.com/a/339409/87808. I am only a beginner so I will need to figure out how I can adapt this to work for me. Here is a MWE, but I had to enter all the indexed words by hand I was hoping to be able to find a way to do a global Find (and then replace) to make the index.
\documentclass[11pt{article}
\usepackage{makeidx}
\makeindex
\begin{document}
\include{intro}
\include{two}
\include{three}
\printindex
\end{document}
The three files are, intro:
\section{Intro}
This chapter will include \index{worms}worms gardens and fleas.
two:
\section{Two}
This bit has \index{worms} worms only
three:
\section{Three}
Loads more \index{worms} worms here.
\indexwith spaces on both sides will result in a too-wide space in that location in the output. – barbara beeton Sep 02 '17 at 23:55
