elasticsearch "having not" query - elasticsearch

Question

Some documents has category fields.. Some of these docs has category fields its value equals to "-1". I need a query return documents which have category fields and "not equal to -1".
I tried this:
GET webproxylog/_search
{
"query": {
"filtered": {
"filter": {
"not":{
"filter": {"and": {
"filters": [
{"term": {
"category": "-1"
}
},
{
"missing": {
"field": "category"
}
}
]
}}
}
}
}
}
}
But not work.. returns docs not have "category field"
EDIT
Mapping:
{
"webproxylog": {
"mappings": {
"accesslog": {
"properties": {
"category": {
"type": "string",
"index": "not_analyzed"
},
"clientip": {
"type": "string",
"index": "not_analyzed"
},
"clientmac": {

Answer 1

If your category field is string and is analyzed by default, then your -1 will be indexed as 1 (stripping the minus sign).
You will need that field to be not_analyzed or to add a sub-field which is not analyzed (as my solution below).
Something like this:
DELETE test
PUT /test
{
"mappings": {
"test": {
"properties": {
"category": {
"type": "string",
"fields": {
"notAnalyzed": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
}
}
POST /test/test/1
{"category": "-1"}
POST /test/test/2
{"category": "2"}
POST /test/test/3
{"category": "3"}
POST /test/test/4
{"category": "4"}
POST /test/test/5
{"category2": "-1"}
GET /test/test/_search
{
"query": {
"bool": {
"must_not": [
{
"term": {
"category.notAnalyzed": {
"value": "-1"
}
}
},
{
"filtered": {
"filter": {
"missing": {
"field": "category"
}
}
}
}
]
}
}
}
