Why are my Lucene Document results empty?

I'm running a simple test--trying to index something and then search for it. I index a simp开发者_运维百科le document, but then when a search for a string in it, I get back what looks to be an empty document (it has no fields). Lucene seems to be doing something, because if I search for a word that's not in the document, it returns 0 results.

Any reason why Lucene would reliably return a document when it finds one that matches the given query, and yet that document has nothing in it?

More details:

• I'm actually running Lucandra (Lucene + Cassandra). That certainly may be a relevant detail, but not sure.

• The fields are set to Field.Store/YES and Field.Index/ANALYZED

• Interestingly, I'm able to get this to work just fine on my local machine, but when we put it on our main server (which is a multi-node cassandra setup), I get the behavior described above. So this seems like probably the relevant detail, but unfortunately, I see no error message to clue me in to what specifically is causing it.

Unsure if this will work with Lucandra, but you have tried opening the index using Luke? Viewing the index contents with Luke might help

It's hard to tell what the problem is since you only provide a very abstract description. However, it sounds a bit like you are not storing the field value in the index. There are different modes for indexing a field. One option determines whether the original value is stored in the index to retrieve it later:
