Graphql query filter in Weaviate

Question

It seems I can't figure out how to query the Weaviate and filter out unwanted objects. I have read: https://graphql.org/learn/queries/#arguments

I think this would translate into my test using postman:

{ 
  "query": "{ 
    Get { 
      Things { 
        Technique(name: "some name of technique in the weaviate") { name, uuid } 
      } 
    } 
  }"
} 

This results I received:

{
  "code": 400,
  "message": "parsing body body from \"\" failed, because invalid character 's' after object key:value pair"
}

How should this work?

To filter out objects in Weaviate you have to use the "where" filter. Take a look here: https://www.semi.technology/documentation/weaviate/current/query-data/filters.html#where-filter.

I think your query in GrapiQL would look something like this:

{"query": "{ Get { Things { Technique ( where: { path: ["name"], operator: Equal, valueSting: "some name of technique in the weaviate"} ) { name, uuid } } } }" }

For a JSON body in a rest POST request, it would look like this (escape the double quotes):

{"query": "{ Get { Things { Technique ( where: { path: [\"name\"], operator: Equal, valueSting: \"some name of technique in the weaviate\"} ) { name, uuid } } } }" }
