Hi!
I'm trying to store and search for products and product variants in
Elasticsearch. I have a set of products (about 4000) and product variants
(all together about 20000) which are related to the products. A product
could be a hole-puncher and it variants are a hole-puncher in green, a
hole-puncher in red… (+different attributes).
In addition I have customers (about 40000). Some of them (about 10000) have
a special range of products (a specific sub-set out of the “product
/product variant pool”). E.g. Client 1 has the hole-puncher in red and
green. Client 2 has the hole-puncher in red and yellow. Client 3 has the
hole-puncher in red. Client 4 doesn’t have the hole-puncher …
In Addition each Client of these 10000 Clients have special Prices for the
product variants and the product variants can have a different
assortment-type (a primary or a secondary product). I have to search for
the products and display the product information + the amount of product
variants. A search result should look like this: Super Hole Puncher The
Description form the product X-Product variants Lowest Price XX
In Addition I have to provide a facettennavigation with product-categories…
and filters. I have to filter for different attributes, the price of a
product variant, the assortment-type.
How would you store the Data? Would you create one index for the products
or would you create one index for each customer with a special product set
(which would result in 10000 Indices).
How would you store the data which is individual for the clients
(product-type + Price). Currently I store the Client information as
nesteted Object, but I don’t know if this is the way I should go. Maybe
seperate columns/fields for each customer? This would cause a document
which have about 10000 fields. What amount of fields can elasticsearch
handle without performance issues?
Sample JSON:
{
"Hole-puncher 5008": {
"MasterArticleNumber": "",
"Title": "Hole-puncher 5008",
"Attributes": {
"Width": "100 mm"
}},"123456": {
"MasterArticleNumber": "Hole-puncher 5008",
"Title": "Hole-puncher 5008 in blue",
"Description": "the description",
"Attributes": {
"Width": "100 mm",
"Color": "blue"
},
"Clients": [
{
"Type": "K",
"Price": 78,
"Client": 1
},
{
"Type": "R",
"Price": 80,
"Client": 2
}
]}, "78977": {
"MasterArticleNumber": "Hole-puncher 5008",
"Title": "Hole-puncher 5008 in black ",
"Description": "the description",
"Attributes": {
"Width": "100 mm",
"Color": "black"
},
"Clients": [
{
"Type": "K",
"Price": 78,
"Client": 1
},
{
"Type": "R",
"Price": 80,
"Client": 2
}
]}}
Currently I'm storing the main product as the parent of the
product-variants because i have to display the parent-product in the search
result. Is it possible to sort the parent product on the lowest matching
price of its childs?
I would be really thankfully for any help /hint
