Update: Actually, what the above search string when set to "Paragraph" is giving me ("32 exact hits") is, oddly enough, every line/entry (i.e., "Paragraph," if I remember it correctly) in Tov-Polak where --+ occurs with another --+. OR... and this is the strange thing... --- shows up in these results, too. So if a line has --+ and ---, it shows as a hit. So, too, does a Paragraph with --+ and +.
If it has just --+, it doesn't highlight in the Paragraph view. So this search string doesn't still quite get me all the way there.
Does the search field matter for such a query? I was doing "Comments" above. Though "Symbols" field yields same results.
Again, I realize that the simplest way to find all instances of --+ in Tov-Polak is to set the search field to "Symbols" and then type in the number 12 (which is --+), but as I noted here, this method has a few kinks--not everywhere, but with some of the notations.
I'm mostly just curious about this thread, how to construct this sort of search, especially for those searches using the "Symbols" field that don't seem work fully properly in the MT-LXX tool.
