| * Provides field types to support for Lucene's {@link NumericField}. |
| * See {@link org.apache.lucene.search.NumericRangeQuery} for more details. |
| * It supports integer, float, long, double and date types. |
| * <p/> |
| * For each number being added to this field, multiple terms are generated as per the algorithm described in the above |
| * link. The possible number of terms increases dramatically with lower precision steps. For |
| * the fast range search to work, trie fields must be indexed. |
| * <p/> |
| * Trie fields are sortable in numerical order and can be used in function queries. |
| * <p/> |
| * Note that if you use a precisionStep of 32 for int/float and 64 for long/double/date, then multiple terms will not be |
| * generated, range search will be no faster than any other number field, but sorting will still be possible. |
