We suggest to use dictionaries which come with openoffice, hunspell,

has better support of composite words.
Thanks, that knocked me onto the right track. To easy to miss the
blindingly obvious at times. :-)
Works beautifully now.
I may have been to quick to declare success.
The following works as expected, returning the individual words:
SELECT
ts_debug('norwegian', 'overbuljongterningpakkmesterassistent'),
ts_debug('norwegian', 'sjokoladefabrikk'),
ts_debug('norwegian', 'epleskrott');
-[ RECORD 1
]--------------------------------------------------------------------------------------------------------------------------------------------------
ts_debug | (asciiword,"Word, all
ASCII",overbuljongterningpakkmesterassistent,"{no_ispell,norwegian_stem}",no_ispell,"{buljong,terning,pakk,mester,assistent}")
ts_debug | (asciiword,"Word, all
ASCII",sjokoladefabrikk,"{no_ispell,norwegian_stem}",no_ispell,"{sjokoladefabrikk,sjokolade,fabrikk}")
ts_debug | (asciiword,"Word, all
ASCII",epleskrott,"{no_ispell,norwegian_stem}",no_ispell,"{epleskrott,eple,skrott}")
But, the following does not:
SELECT
ts_debug('norwegian', 'hemsedalsdans'),
ts_debug('norwegian', 'l?rdalsbrua'),
ts_debug('norwegian', 'hengesmykke');
-[ RECORD 1
]----------------------------------------------------------------------------------------------------
ts_debug | (asciiword,"Word, all
ASCII",hemsedalsdans,"{no_ispell,norwegian_stem}",norwegian_stem,{hemsedalsdan})
ts_debug | (word,"Word, all
letters",l?rdalsbrua,"{no_ispell,norwegian_stem}",norwegian_stem,{l?rdalsbru})
ts_debug | (asciiword,"Word, all
ASCII",hengesmykke,"{no_ispell,norwegian_stem}",norwegian_stem,{hengesmykk})
Would this be due to a limitation in the dictionary, or a
misconfiguration on my side?
sorry, I don't know norwegian, what do you mean ? Did you complain that
no_ispell doesn't recognize these words ?
Yes, I'm sorry, I should have explained better.
The words hemsedalsdans, hengesmykke and lærdalsbrua, are
"concatenations" of the words Hemsedal and dans, henge and smykke and
Lærdal and bru. Hemsedal and Lærdal are in fact geographic names, so I'm
not sure it would handle that at all anyway. Both parts of the word,
hengesmykke, is in the dictionary though, ie. both henge and smykke. It
seems that some words it is able to properly spilt, and then some it
doesn't recognise.
The problem I'm trying to work around, is that as far as I can tell,
tsearch doesn't support truncation, ie. searching for "*smykke" or
"hemsedal*" etc.
