[Hibernate Search] Question regarding @IndexedEmbedded

jmluy · **Joined:** Wed Aug 22, 2007 5:37 am **Posts:** 1

I'm using Hibernate Search 3.0.0 Beta 3 and i was wondering if something like the following is possible. I'm trying to do this but can't seem to make it work.

Code:

@Indexed(index = "classa")
Class A
{
   @IndexedEmbedded
    List<ClassB> bList;
}


@Indexed(index = "classb")
Class B
{
   @IndexedEmbedded
    List<ClassC> cList;
}

@Indexed(index = "classc")
Class C
{
   @Field(index = Index.TOKENIZED, store = Store.NO)
   String name;
}

then my query is something like:
bList.cList.name:xxx

Is this possible?

BTW I'm using Beta4

From the document

Quote:

@IndexedEmbedded is supported on collections too (ie to index associated object included in collections).
But the support is only partially implemented. It will depend on how you update collections
(Check HSEARCH-56 in JIRA for more informations). The workaround is to manually index the object
(session.index())

But it does not work even without collections. In my case, fields from Class C objects are not added to Class A indices however I can access Class B fields. I thought the depth was defaulting to 1 so I defined depth=2 in Class A but still the same problem. I just want to have Class B and Class C as part of Class A index. Do I still need to add to @Indexed to Class B and Class C?

Code:

@Indexed
Class A
{
   @ManyToOne
   @IndexedEmbedded
    B bObject;
}


Class B
{
    @Field
     String name;

    @ManyToOne
    @IndexedEmbedded
     C cObject;
}


Class C
{
    @Field
    String name;
 
    @Field
    String title;
}

It works after I make the following changes. I'm not sure if it would work for collections but you could try and post your results.

Ideally I would expect depth=2 in Class A to work but for some reason I have to define the depth in Class B. May be I don't understand the usage of depth.

To answer my other question, other classes(B &C ) need not have @Indexed.

Hope it helps others using hibernate search.

Code:

@Indexed
Class A
{
   @ManyToOne
   @IndexedEmbedded
    B bObject;
}


Class B
{
    @Field
     String name;

    @ManyToOne
    @IndexedEmbedded(depth=1) /*** Modified ***/
     C cObject;
}


Class C
{
    @Field
    String name;
 
    @Field
    String title;
}

This might be a bug, can you post your test to JIRA, I need to check it out.
