Anıl Çetin commented on SOLR-64:
--------------------------------
Sorry I couldn't explain it I think;
for:
a_level1/a_level2/a_level3/a_level4
and
b_level1/b_level2/b_level3/b_level4
result:
a_level1
--> a_level1/a_level2
------> a_level1/a_level2/a_level3
-----------> a_level1/a_level2/a_level3/level4
b_level1/a_level1/a_level2/a_level3/level4
--> b_level1 / b_level2 / a_level1/a_level2/a_level3/level4
------> b_level1/b_level2/b_level3/ a_level1/a_level2/a_level3/level4
----------->
b_level1/b_level2/b_level3/b_level4/a_level1/a_level2/a_level3/level4
Actually it mixes the fields. Also, in some indexes (I don't know what
causes/why) it gives error
