Libronix allows proximity to be specified by a certain number of words, characters, clauses, sentences or paragraphs. As far as I can see the only proximity unit is words in Logos 4 and 5. Are the other proximity units available?
I realize that the Logos 4/5 word proximity is far more useful than the similar feature in Libronix, because it meatures an actual number of words, rather than an estimated number of words based on the number of characters between search terms. But I wonder if the other proximity units are implemented or planned.
