Noble Paul commented on SOLR-877:
---------------------------------
bq.have you done any performance testing of this approach versus the radix tree
(or other tree/trie approaches)?
I haven't done a perf comparison. But , it occurred to me as I looked at the
code .It goes through each Term one by one and does a startsWith()
It can be quite expensive for large no:of Terms
Memory consumption can be a problem.
That is why I suggested a config param. User can make a call as to whether he
wants to pay that price and he can afford that.

> I wrote a simple SearchComponent on the plane the other day that gives access
> to Lucene's TermEnum capabilities. I think this will be useful for doing
> auto-suggest and other term based operations. My first draft is not
> distributed, but it probably should be made to do so eventually.
