Uwe Schindler updated LUCENE-3065: ---------------------------------- Comment: was deleted (was: Ideally this could be done with the schema-like approach of one of the GSoC projects? We already discussed about that: We can use the FieldsReader/FieldsWriter type flag (which currently says, binary/text and compressed (unused now)) in the index file format to mark a field as NumericField. In that case, Document.getField() would return the NumericField instance. For Lucene backwards we should still support creating "text-only" fields. The new binary format would also be compatible with solr, as on getField, Solr would get a NumericField and can decide using instanceof what to do. Old Solr indexes without the NumericField marker flag would return as byte[], in which case, solr would do the decoding. For storing on index side, Solr could move to NumericField completely (I dont like the current approach using NumericTokenStream and to/fromInternal wrappers around conventional Field).) > NumericField should be stored in binary format in index (matching Solr's > format) > -------------------------------------------------------------------------------- > > Key: LUCENE-3065 > URL: https://issues.apache.org/jira/browse/LUCENE-3065 > Project: Lucene - Java > Issue Type: Improvement > Components: Index > Reporter: Michael McCandless > Assignee: Uwe Schindler > Priority: Minor > Fix For: 3.2, 4.0 > > Attachments: LUCENE-3065.patch, LUCENE-3065.patch, LUCENE-3065.patch, > LUCENE-3065.patch, LUCENE-3065.patch, LUCENE-3065.patch, LUCENE-3065.patch > > > (Spinoff of LUCENE-3001) > Today when writing stored fields we don't record that the field was a > NumericField, and so at IndexReader time you get back an "ordinary" Field and > your number has turned into a string.
