Find/replace a field variable?

[onmotry]

Hello,

I have a long text (150K words) and I'd like to be able to number the occurrences of a certain word (say lambda). I would like for the nth lambda in the text to show up as "n lambda"

So basically, I want to insert an incrementing number field in front of every lambda in the text. I can't figure out how to put the field in the replace box, however. I was wondering if there's a way to do this.

Thank you!

I suspect you will need a macro or a field connected to a database.

Here's a macro that numbers the word "the" as "(n) the".
