&& operator in JSONpath ()

Below is the sample json from the tutorial

{
"store": {
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}


I am trying to check for the objects with the following condition

$..[?(@.price == 12.99 && @.title == 'Moby Dick')]


which should have retrivd me as shown below. But, it only shows [].

{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},


Any pointers as to where in the query is the error?

Answer

You should use || instead of &&, since you want objects with either price (not both, which is impossible):

$..[?(@.price == 12.99 || @.price == 8.99)]
