Index not building on cloned site

I have copied our site to a dev setup, and I went to rebuild the index because I was not getting any search results… but the process always says:

Wiping out the index… Counting posts… 817 posts found.
Indexed 0 posts (total 0), processed 817 / 817.
Indexing complete. 817 posts excluded.

Why is it excluding all of my posts? Everything is properly indexed on the site this one is cloned from.
