I am running a web script in two identical versions (identical as in "cut and paste"), one via RESTXQ and one vi REST. The response is different, and I wondered what may be the trouble.

For example the output (the URLs only works locally) for
    http://ljohnsen:8984/hyphens/mellom
is the same as
     http://ljohnsen:8984/rest?run=hyphen-show.xq&word=mellom

which is a set of hyphenation data:
    mellom
    mel - lom 17005
    Mel - lom 144
    mel - lom. 50

but if "mellom" is exchanged with "nasjonalbiblioteket" only  the REST version shows any result, which then is the same as I get experimenting in the GUI. 

The actual script is added below, and which runs in both versions  (identical apart form the rest and restxq interfaces), it uses full text search, but results differ when run under the REST-regime. 

All the best
