[chef] index questions

[Nick < >]

I have some questions about the Chef Index.  I'm just using it to search for 
nodes; I'm not trying to do any fancy custom indexes.

1) When I use the search() function in a recipe, or if I make a REST request 
to "/search/node?..." , I get back multiple copies of each node.  It appears 
each time time a node is saved (which happens multiple times during each 
run), a new copy is added to the index, instead of the new node overwriting 
the old one.  Has anyone else noticed this behavior?  Am I doing something 
wrong?

2) Nodes never seem to get removed from the index.  If I delete a Node via 
the web UI, or if I make a REST request to "/delete/node/...", the node is 
deleted, but it remains in the index.  Or at least, the node is still 
included in search results.  (It appears that the hook for this the 'destroy' 
method in node.rb; a quick grep of the source doesn't find a reference to 
this anywhere.)

Are there additional steps that need to be done in order to maintain the 
index?
