It's a well known problem that JVS is meant to be a Lojban2English (or to any other language) dictionary, not vice versa.
Some English words that people are searching for can't appear in JVs since they are expressed using word combinations in Lojban.
Adding new lujvo is not an option: why should we relex English when already existing words can do the trick?
La Muplis (or
tatoeba.org, its database) isn't exactly what needed since people are used to dictionaries with isolated words.
So I propose to allow adding these word combinations to JVS:
"TAG brivla", "NAhE brivla".
You may propose allowing other combinations as well.
