Sorry for top posting, but I have no additional info on this.
BTW I need to refresh the question as I have tried squat, and I'm biting the dust with the already known problems
( "Corrupted squat uidlist file" or "Panic: file squat-trie.c:" ).
Is there some pointer on where/how to find assist on fts-lucene to keep on analisys for this problem on sparc ?
T.I.A.
