boolean value in FlureeQL Query

[keispace]

Hello, I'm testing the fluree query, but if I run the query below, I don't get the result I want.
To be precise, "public":true produces normal results, but "public":false will return both false and true.
It seems that the non-value and false are handled together, similar to the null, undefined, and false of the javascript.

Is there a way to check only false value?

query json

{
  "@context":{"ex": "http://example.org/", "schema": "http://schema.org/", "f": "https://ns.flur.ee/ledger#", "rdfs": "http://www.w3.org/2000/01/rdf-schema#"}
  "from": "test/test",
  "where": 
    {
      "@id": "?s",
      "@type":"Event",
      "ex:public":true             // if set fasle, both false and true will come out
    },
  "select":{"?s":["*"]}
}

this is 'create json' of sample data

{
  "@context":{"ex": "http://example.org/", "schema": "http://schema.org/", "f": "https://ns.flur.ee/ledger#", "rdfs": "http://www.w3.org/2000/01/rdf-schema#"}
  "ledger": "test/test",
  "insert":[
    {"@id":"2489651045","@type":"CreateEvent","ex:public":false,"ex:created_at":"2015-01-01T15:00:00Z"}
    ,{"@id":"2489651051","@type":"PushEvent","ex:public":true,"ex:created_at":"2015-01-01T15:00:01Z"}
    ,{"@id":"Event", "@type":"rdfs:Class"},
    {"@id":"PushEvent", "rdfs:subClassOf":{"@id":"Event"}},
    {"@id":"CreateEvent", "rdfs:subClassOf":{"@id":"Event"}},
]}

Hi @keispace, that indeed seems like a bug. It may be related to issue #522 (already fixed), but in this case, the issue lies within the where clause.

Although, you can leverage that functionality by using filters on a logical variable.

{
    "@context": {
        "ex": "http://example.org/",
        "schema": "http://schema.org/",
        "f": "https://ns.flur.ee/ledger#",
        "rdfs": "http://www.w3.org/2000/01/rdf-schema#"
    },
    "from": "test/test",
    "where": [
        {
            "@id": "?s",
            "@type": "Event",
            "ex:public": "?public"
        },
        [
            "filter",
            "(not ?public)"
        ]
    ],
    "select": {
        "?s": [
            "*"
        ]
    }
}
