4.2. Mapping Properties Multiple Times
4.2. Mapping Properties Multiple Times Properties may need to be mapped multiple times per index, using different indexing strategies. For example, sorting a query by field requires that the field is not analyzed. To search by words in this property and also sort it, the property will need to be indexed it twice - once analyzed and once un-analyzed. @Fields can be used to perform this search. For example: Example 4.3. Using @Fields to map a property multiple times In the example above, the field summary is indexed twice - once as summary in a tokenized way, and once as summary_forSort in an untokenized way. @Field supports 2 attributes useful when @Fields is used: analyzer: defines a @Analyzer annotation per field rather than per property bridge: defines a @FieldBridge annotation per field rather than per property Report a bug
@Indexed(index = "Book") public class Book { @Fields( { @Field, @Field(name = "summary_forSort", analyze = Analyze.NO, store = Store.YES) }) public String getSummary() { return summary; } }
