I believe that there's a problem with the advanced seraches under jEmplode v36. If you have open the console where it started from (a problem under some OSes, I realize), I believe you'll see it throw a non-fata exception having to do with some string library. Mike's told me it'll be fixed in v37. Maybe it already is in his pre-v37 pseudo-release, which I haven't bothered to check yet. Search the forum for tfabris-jemplode, IIRC. Edit: Hyah 'tis.
