@Deprecated public class UninvertingReader extends FilterLeafReader
This is accomplished by "inverting the inverted index" or "uninversion".
The uninversion process happens lazily: upon the first request for the
field's docvalues (e.g. via LeafReader.getNumericDocValues(String)
or similar), it will create the docvalues on-the-fly if needed and cache it,
based on the core cache key of the wrapped LeafReader.

BinaryDocValues |
getBinaryDocValues(String field)
Deprecated.
Returns
BinaryDocValues for this field, or
null if no BinaryDocValues were indexed for
this field. |
Object |
getCombinedCoreAndDeletesKey()
Deprecated.
Expert: Returns a key for this IndexReader that also includes deletions,
so CachingWrapperFilter can find it again.

Deprecated.
Expert: Returns a key for this IndexReader, so CachingWrapperFilter can find
it again.
|

getDocsWithField(String field)
Deprecated.
Returns a
Bits at the size of reader.maxDoc(),
with turned on bits for each docid that does have a value for this field,
or null if no DocValues were indexed for this field. |

Get the
FieldInfos describing all fields in
this reader. |
NumericDocValues |
getNumericDocValues(String field)
Deprecated.
Returns
