[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-682) DSL cannot handle fieldBridge for @IndexEmbedded fields

DSL cannot handle fieldBridge for @IndexEmbedded fields ------------------------------------------------------- Key: HSEARCH-682 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-682 Project: Hibernate Search Issue Type: New Feature Components: query Affects Versions: 3.3.0.Final Environment: Hibernate 3.6.0, HSearch 3.3.0, Mysql 5.1.52. Reporter: Nick Fenwick Fix For: 4.0 Attachments: HSEARCH-682-unittest1.tgz Discussed in https://forum.hibernate.org/viewtopic.php?f=9&t=1009440, "Re: Correct to use ignoreFieldBridge for "subentity.field" DSL?". I find I have to set ignoreFieldBridge when querying for a field indexed using @IndexEmbedded, i.e.: {code}@Entity class CategoryEntity { @Column(name="lft") @Field(name="left", index=Index.UN_TOKENIZED, store=Store.YES) @FieldBridge(impl=PadNumberBridge.class, params = { @Parameter(name="pad", value="4") } ) private int left; ... same for 'right' ... } @Entity class ItemEntity { @IndexedEmbedded(depth=1) private CategoryEntity category; }{code} results in fields for ItemEntity being stored in the Lucene index like: {code} category.left = 0004 category.right = 0012 {code} To query for these, I cannot do: {code} qb.range().onField("category.left").above(4).createQuery() {code} I get an exception saying it doesn't know what FieldBridge to use for "category.left". Instead, I can do: {code} qb.range().onField("category.left").ignoreFieldBridge().above(4).createQuery() {code} but the 'value' is no longer padded according to the FieldBridge that was specified in CategoryEntity for its 'left' attribute, I have to pass value as e.g. "0004". It would be good to mention this situation in the documentation (5.1.2. "Building a Lucene query with the Hibernate Search query DSL"), at least to specify that it is/isn't supported, so that people attempting this kind of @IndexEmbedded mapping know how to safely build a query for such fields.
