Here's a cool little trick that will yield more accurate results. You can't search for all inflected forms directly in the MT-LXX module, but you can use the "Merge" command to link the HMT and LXX Texts to the MT-LXX.
Select "Show Text As" Paragraphs and add Titles to display only the lines in the MT-LXX that contain the hits you're looking for. Also, set the Search Scope to "Paragraph".
That is one thing I knew and use pretty regularly. And as I can see from your count, this method still produces the wrong statistical information. Take a look at a small book, like Habakkak, and I expect that you will find a much higher count than you do find in the actual results. Note: searching for either kurios or YHWH alone produces the correct statistics, but together the count is far too high. When combining together with an <AND> the numbers should go down and not up.
What I didn't know until yesterday is that I can limit the search to "paragraph" with the "search scope" button and only search for matches in the translated words. I also had not realized that I could add a second search line to the same LXX-MT tab to search both Hebrew and Greek in the same tab.
