I like to Bible search using the analysis view via the "asterisk" which yields any and everything within the scope you select.
I will pick a book of the Bible to study and run this so to see how many times a word comes up. it is helpful, but I am not sure it works on every Bible.
I have found it to work well on the ESV, but the NASB doesn't work, or at least I haven't run it long enough to work.
Additionally, I find sometimes it will say there are two occurrences of a word, if I run this on a single verse, when in the Greek (or Hebrew) and English, there is only one occurrence and no article say for a noun. Strange.
At the end of it all, I did reindex my entire library, but I am thinking that I may need to reinstall L4 completely. This type of searching used to work fine for anything, but lately has gotten real picky.
Perhaps some of the Logos techies lingering out there can provide some insight.
Thanks.
