Hello Ryan,

reindexing won't cause any waste in sphinx, so go ahead.

Btw. you have several main indices, eg. main1, main2, etc. It's possible to use 
main1 for 2017 data, main2 for 2018 data, etc. In that case you may move main1 
to a backup media to free up some space. The trick is to fix both 
indexer.delta.sh and indexer.main.sh to reference the given main index.
