All I can see when I look at the module using DB Browser for SQLite is the following:
<p><b>Total KJV occurrences: 12</b></p>
In other words, there is no special link (the "p" tag just marks a paragraph, and the "b" tag marks bold text), which leads me to conclude that the search function is programmed right into e-Sword (by the way, I didn't know that that was a link that performed a search, so thanks for the tip! It works on the Mac as well as on the iPhone).
The only suggestion I can think of would be to add this same or similar text to the end of each entry in your lexicon module. e-Sword may automatically make it a link that will work in the same way as the Strong's module. Try it on an entry or two and see if it works.
Best of luck.
P. S. — I would also mention another way you can see all instances of a particular Greek or Hebrew word in the Bible, and that is to use the KJC (King James Concordance) lexicon which can be downloaded right within e-Sword. If, say, you have looked up G1689, then if you go to this lexicon, it will show you a list of every verse which contains that word. And if you are using the popup (which I think you are) you can have this lexicon show up right under Strong's or before it or whatever you like. You might find this approach useful as well.
