I use vim-latex. For the sake of SyncTeX, I usually format my paragraphs into separate lines, using a customized gqip.
I used to put \index after the term to be indexed, as suggested here. For example
Bla bla bla bla bla bla bla bla bla bla. A
\emph{quasipseudometaball}\index{quasipseudometaball} is defined as follows
However, this produces a long string without spaces, which is not practical when I format the paragraph in Vim with gqip, as shown in the example above.
Putting space or line break before \index is not a good idea, neither, because
Let $B$ be a ball \index{ball}.
will put a space before the period. Anyway, putting \index within the text makes the defining paragraphs unreadable in the source code. I don't like it.
I now decide to put them before the relative paragraphs, but sometimes the paragraph is long, and the location is not precise anymore.
It may be a silly question, but I would like to know where do you put \index?
\indexinside a macro. So instead of doingball\index{ball}I'll do\term{ball}or something similar and then define\term(or whatever) to use\index. (Although that additionally requires escapingmakeindexspecial characters etc, unless I use\usepackage[index]{glossaries}which does it for me.) – Nicola Talbot Mar 12 '14 at 15:03cats\index{cat}.orcats.\index{cat}- the second seems to work better. – bombcar Mar 23 '14 at 23:11\indexbefore the paragraph that contains the keywords? I guess most people just start reading a paragraph from the beginning. – Leonardo Castro Feb 9 '16 at 20:25
