LUCENE-2380: FieldCache.getStrings/Index --> FieldCache.getDocTerms/Index * The field values returned when sorting by SortField.STRING are now BytesRef. You can call value.utf8ToString() to convert back to string, if necessary. * In FieldCache, getStrings (returning String[]) has been replaced with getTerms (returning a FieldCache.DocTerms instance). DocTerms provides a getTerm method, taking a docID and a BytesRef to fill (which must not be null), and it fills it in with the reference to the bytes for that term. If you had code like this before: String[] values = FieldCache.DEFAULT.getStrings(reader, field); ... String aValue = values[docID]; you can do this instead: DocTerms values = FieldCache.DEFAULT.getTerms(reader, field); ... BytesRef term = new BytesRef(); String aValue = values.getTerm(docID, term).utf8ToString(); Note however that it can be costly to convert to String, so it's better to work directly with the BytesRef.
