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', 'lærdalsbrua'),
  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",lærdalsbrua,"{no_ispell,norwegian_stem}",norwegian_stem,{lærdalsbru}) 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?

Commands used are as follows:

CREATE TEXT SEARCH DICTIONARY no_ispell (
TEMPLATE = ispell,
        DictFile = nb_NO,
        AffFile =  nb_NO,
        StopWords = norwegian
);

and

ALTER TEXT SEARCH CONFIGURATION norwegian ALTER MAPPING FOR asciiword, asciihword, hword_asciipart,word, hword, hword_part WITH no_ispell, norwegian_stem;
