Hello,
One approach (not a solrish one, but still) would be to use Lucene API and
set up an IndexReader onto the solr index in question. You can then do:
[code]
Directory indexDir = FSDirectory.open(new File(pathToDir));
IndexReader input = IndexReader.open(indexDir, true);
FieldSelector fieldSelector = new SetBasedFieldSelector(
null, // to retrive all stored fields
Collections.<String>emptySet());
int maxDoc = input.maxDoc();
for (int i = 0; i < maxDoc; i++) {
if (input.isDeleted(i)) {
// deleted document found, retrieve it
Document document = input.document(i, fieldSelector);
// analyze its field values here...
}
}
[/code]
I haven't compiled this code myself, you'll need to experiment with it.
