Noble Paul commented on SOLR-1437:
----------------------------------
the putNulls are very important . I can probably add a testcase for that and
probably it will be evident to you.
one another concern I have with the patch is that every node which is not
relevant results in walking up the tree to figure out if there was a wild-card
. So even if somebody does not use wild-cards he ends up paying the price. Each
node can keep a boolean flag if that branch has a wild-card upstream and this
flag has to be set at the time of building the tree.
