Hello everyone!

I cannot get this to work. Neither in a german version, nor with the
norwegian example supplied on the tsearch website.
That means, just like Hannes I can get compound word support without
inserted 's' in german and norwegian:
"Vertragstrafe" works, but not "Vertragsstrafe", which is the right
Form.

So I tried it the other way around: My dictionary consists of two words:

---
vertrag/zs
strafe/z
  ---

My affixes file just switches on compounds and allows for s-insertion
as described in the norwegian tutorial:

---
compoundwords controlled z
suffixes
flag s:
   [^S] > S              # endet nicht auf "s": "s" anfuegen und in
compound-check ("Recht" > "Rechts-")
---

ts_debug yields:

tstest=# SELECT tsearch2.ts_debug('vertragstrafe strafevertrag
vertragsstrafe');
                                       ts_debug
------------------------------------------------------------------------
-------------
(german,lword,"Latin
word",vertragstrafe,"{ispell_de,simple}","'strafe' 'vertrag'")
(german,lword,"Latin
word",strafevertrag,"{ispell_de,simple}","'strafe' 'vertrag'")
(german,lword,"Latin
word",vertragsstrafe,"{ispell_de,simple}",'vertragsstrafe')
(3 Zeilen)

I would say, the ispell compound support does not honor the s-Flag in
compounds.
Could it be, that this feature got lost in a regression? It must have
worked for norwegian once. (Take the "overtrekksgrilldresser" example
from the tsearch2:compounds tutorial, that I cannot reproduce).

Any hints?

Alexander
