Hi,
I found a own hack. It's based on free interpretation of the function
strdist().
Have:
- one multivalued field 'part_of'
- one unique field 'groupsort'
Index each item:
For each group membership:
add groupid to 'part_of'
concat groupid and sortstring to new string
add this string to a csv list
End
add the csv list to 'groupsort'
End
Have also, a own class that implements
org.apache.lucene.search.spell.StringDistance, to generate a custom
distance value. This class should:
- split the csv list
- find the element/string that starts with the given group id
- translate the rest (sortstring) to a float value
.../select?q=part_of:X&sort=strdist("X", groupsort, FQN) asc
FQN is the fully qualified name of the own class. (remember to place the
the jar in a 'lib' defined in solrconfig.xml or add a own 'lib' entry)

(still looking for a smarter solution)
