[hibernate-issues] [Hibernate-JIRA] Created: (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: engine
Affects Versions: 3.3.0.Final
Environment: Hibernate 3.6.0, HSearch 3.3.0, Mysql 5.1.52.
Reporter: Nick Fenwick
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.
