Hi, I am trying to query elasticsearch in order to find out what products were bought with a certain product.
My data going into logstash from a flat file.
OrderNumber ProductName
order1 Chicken
order2 Banana
order3 Chicken
order1 Cucumber
order2 Chicken
order3 Apples
order1 Flour
order2 Rice
order3 Nuts
As you can see above i have an Product Name of Chicken which occurs in different Order Numbers.
OrderNumber ProductName
order1 Chicken
order3 Chicken
order2 Chicken
This is what i would like to achieve :
Step 1 : Lookup all order Numbers that contain chicken
OrderNumber ProductName
order1 Chicken
order3 Chicken
order2 Chicken
Step 2 : if the above orders have chicken in it give me all the other products that was also purchased with it
Result :
OrderNumber ProductName
order1 Cucumber
order2 Banana
order3 Apples
order1 Flour
order2 Rice
order3 Nuts
This is what i have tried so far for Step1 :
Query
{
"query" : {
"match" : {
"ProductName" : "Chicken"
}
}
}
Result
"hits" : {
"total" : 3,
"max_score" : 11.378191,
"hits" : [ {
"_index" : "hello",
"_type" : "logs",
"_id" : "AVmxaChupyZuCjD89xPX",
"_score" : 11.378191,
"_source" : {
"message" : "order1\Chicken\r",
"path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
"OrderNumber" : "order1",
"ProductName" : "Chicken\r"
}}, {
"_index" : "hello",
"_type" : "logs",
"_id" : "AVmxaChupyZuCjD89xPX",
"_score" : 11.378191,
"_source" : {
"message" : "order3\Chicken\r",
"path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
"OrderNumber" : "order3",
"ProductName" : "Chicken\r"
}
}, {
"_index" : "hello",
"_type" : "logs",
"_id" : "AVmxaChupyZuCjD89xPX",
"_score" : 11.378191,
"_source" : {
"message" : "order2\Chicken\r",
"path" : "C:\\utils\\Elk\\logstash\\bin\\product.log",
"OrderNumber" : "order2",
"ProductName" : "Chicken\r"
}
I'm very confused as to how to go about completing step 2 as I am very new to Elasticsearch, please help ?
Thanks
