add

@Deprecated
public static void add(NutchDocument doc,
                                  Field f)

Deprecated. Use NutchDocument.add(String, String) instead and set index-level metadata for field information.

Adds a lucene field.

This method is provided for backward-compatibility with older indexing filters. This should not be used by newer implementations since this is slower than NutchDocument.add(String, String) and will be removed in a future release.

Parameters:

f - Lucene field to be added.
