I thought that L4 didn't support regular expression searches but it appears that it might at least partially. Either way there are some odd results. The following examples are from the AFAT.
- lemma:/.(.)\1/@v - 1621 (Libronix gets 1702 occurrences, perhaps I missed a database revision?)
- I then tried lemma:/.(.)\1/@Vc and lemma:/.(.)\1/@Vb both searches got 1621 results
It seems that this search partially work in that I can construct a search that finds Verba Geminata but if I try to limit any way beyond that the search ignores my further parameters.
Here is the thread where this was discovered: http://community.logos.com/forums/t/19904.aspx
