Incorrect display of xs:date index keys

[JonathanRowell]

In Browse Indexes the position, documents and frequency are all perfectly correct, but under the column "term" only a question mark is displayed.

@JonathanRowell Thanks for posting this.

Just to help me/others remember, here was my initial assessment on exist-open:

My guess is that Lucene stores these date and dateTime values in a slightly different format - as some type of number, rather than the original XSD format from your data. When retrieving the index keys from the index, I didn't account for the mismatch in data. The relevant code is here:

@wolfgangmm Do you think there's any hope of retrieving the original date or datetime values, or is the act of indexing them irretrievably altering the source data for the purposes of querying by lucene?
