Hi
I have a document structure as follows
productId, productName, [ {tag1, tag_name, price, tag_category}, {tag2,
tag_name, price, tag_category}, ...]
where tags is a nested document within a product. Each product is a unique
item, but different merchants can sell the same product (called tags) so
the price is different and hence the popularity is also different.
Here are my questions
1. I would like to filter the products by tag_category. I read that nested
filter can do this for me. In addition to returning all the products with a
particular tag_category, can it also return only the tags with the
specified tag_category within a product ?
2. Is there a way to sort the tags (nested documents) by tag price ? with
or without the tag_category constraints
3. In my index each product can have an average of 100 tags and i have 10m
products and 1bn tags in total. Would you recommend nested document
approach or parent-child approach. From what i have read till now I felt
nested document is better.
Thanks
Srini
