Hibernate Search IndexedEmbedded

Hi, there is an Problem.

I have create an Indexed Class like this

Code:

class Holder{
  @IndexedEmbedded
  Set<MyKey> keys = new HashSet<MyKey>();
}

the Key is something like this:

Code:

class MyKey{
  public MyKey(char c,int i){ this.c=c; this.i=i; }
  char c;
  int i;
}

now i have created some instances and indexed them:

Code:

Holder holder = new Holder();
holder.keys.add(new MyKey('a',1));
holder.keys.add(new MyKey('b',2));
holderService.save(holder);

This works fine and no Problems occurred up to this Point. But if I try to search for an holder which contains a key with c:'a' and i:2 I find the example-holder. Is there a possibility to avoid this? I need to search for only these objects where the two values are in ONE Key.

As you are doing you put the 2 parts of the key separated in the index, and mix them with the other fields of other keys: you'll get a bag of chars and ints, without any relation; so the query is going to look for the two values, not necessarily related to the same key.

You want to keep them related in pairs: I'd suggest defining a ClassBridge on "MyKey" to create a single-string encoding of char+int,
or using a FieldBridge on the Set itself returning something like "a1 b5 v7 h7" and have the field tokenized on whitespaces.

With both solutions however you'll need to search for something like "keys:a1" , not separating the two values; this seems more correct IMHO, if the key is defined like that you need one string to identify it.

Thanks for your Reply.

I did a Workaround like this already. The example was very abstract, in reality there are two texts.

But for now it looks like I have to live with it.
