Subject Re: Retrieving indexed field data
Date Mon, 03 May 2010 13:55:22 GMT
If you're asking if indexed but NOT stored data can be retrieved,
i.e. if you can reconstruct the original field(s) from the indexed
data alone, the answer is no. Or, rather, you can, kinda, but it's
a lossy process.

Consider stemming. If you indexed "running" using stemming,
the term "run" is indexed. Lucene/SOLR has no record
of the original term. Similarly with stopwords.

But if you *store* the data, then the original can be retrieved.
