ElasticSearch: Filtering a Complex Query - elasticsearch

Question

I have a complex query in Elasticsearch (below) and I need a pretty basic filter to filter out all "resultat" (results) where the value = 1. (resultat is a numeric field).
I've tried using the "must_not" term in the code below, which was found here and while it does not cause errors, it still does not seem to properly filter the results.
I am using ElasticSearch 2.3.5 with Lucene 5.5.0.
var searchQuery = {
index: "resultats_" + env,
body: {
size: 0,
query: {
filtered: {
query: {
match_all: {}
},
filter: {
query: {
bool: {
should: [{}],
must: [
{
term: {
player_id: {
value: params.player_id
}
}
},
{
term: {
classes: {
value: params.grade
}
}
}
],
must_not: [
{
term: {
resultat: {
value: 1
}
}
}
]
}
}
}
}
},
