Properties to search

Hi,

I have two entitites ClassA and ClassB. The following shows how they look like

Code:

class A {
 
  String name;

  Set<B> collectionOfBs = new HashSet<B>();

}

Code:

 class B {
    String desc;
    
    Class A a;
 }

Now when I set up my search code and pass the properties is the following acceptable:

Code:

new String[]{"name", "desc"};

or does it need to be:

Code:

new String[]{"name","collectionOfBs.desc"}

I have tried both and I am able to search using both ...but I'm not sure what the practice should be...any help would be appreciated.

Are both classes A and B marked as @Indexed?
Do you specify which type of entities you are searching?

What does the code look like? I don't understand what you are going to do with that array.

Hi
Both classes A and B are annotated with @Indexed. I plan to use the array to do the following:

Code:

MultiFieldQueryParser parser = new MultiFieldQueryParser(new String[]{"name","collectionOfBs.desc"}, 
  new StandardAnalyzer());
Query query = parser.parse( "xyz" );

For argument sakes lets presume I will be passing A as an entity to searched on. Hope that is enough info.

Hi,
in theory when searching "B" entities the property should be in the index named as "desc",
for "A" objects the linked property should be written as "collectionOfBs.desc".

In practice I didn't test it, also you may override this naming scheme using annotations.
I would suggest you to look in your index using luke, it may clarify the index structure:

Hi,

Thanks for your reply. In that case if I was doing the following:

Code:

org.hibernate.Query hibQuery = fullTextSession.createFullTextQuery( query, A.class , B.class);

then I would need to specify the following properties:

Code:

new String[]{"collectionOfBs.desc", "desc"}

"desc" being a property on class B.
