I believe I saw an issue like this a while back in 1.6.2, when issue date was missing the trailing ā€˜Zā€™.

My very wild guess would be that it's related to a value in date issued that breaks the creation of the index on this value.


That's a very good guess! I haven't yet gotten around to building a dspace with some more debugging around the search code to see what's actually happening, but this is very plausible.


Looking the our DB,  there were a few non-ISO format dates, and a couple nulls. I updates the bad format dates, removed the nulls, and reindexed, but search by date issued still doesn't work. Do all the dates need to be in a more specific format? (like full ISO: 2000-01-12T12:13:14Z).
