Hi, I'm looking for a nested mapping and index example.What i want is to a have 3 entities: 1. product [title, description, brand,etc] 2. offer [price, availability] 3. review [rating, reviewdescription] product has 1 or more offers product has 0 or more reviews I'm just not sure how to relate these entities through mapping and how to index them. I assume you can index them seperatly but you would need a reference to a parent. Hope someone can point me in the right direction.

Hi, from my understanding you cant index the nested objects separatly, that would be a parent/child relation, not a nested object.

Sometimes, you’re better off … Your mapping could look like this: mappings: { product: { properties: { title: { type: string } description: { type: string } brand: { type: string } offer: { properties: { price: { type: float } availability: { type: whatever } } type: nested } review: { properties: { description: { type: string } rating: { type: float } } type: nested } } } } Am Dienstag, 30.
