im looking for the bug in the following query, as it doesn't bring any results. i want it to act like terms filter, and look for exact values in the country / device fields
```
GET idx/type/_search
{
"query": {
"filtered": {
"filter": {
"and": {
"filters": [
{
"query": {
"query_string": {
"query": "country:\"united kingdom\" AND device:\"desktop\""
}
}
}
]
}
}
}
}
}
```
specifically, this works:
```
"query": {
"query_string": {
"query": "\"united kingdom\""
}
}
```
but this doesnt work:
```
"query": {
"query_string": {
"query": "country:\"united kingdom\""
}
}
```

Hi,
This query is basically a match all that filters on country and device. You can use a simple boolean query with 2 `must` clauses, each clause being a `match` query (or `term` query if your fields are not\_analyzed)

i want to filter on not\_analyzed field with case insensitive filter.
i think i have 3 options:
1. reindex with another mapping
2. use script filter
3. query\_string filter
i've edited the original post, with what exactly doesnt work

Can you please give us your mapping?
The `query_string` query can be very trappy, I personally prefer to use a combination of`bool`, `match` or `term` queries.
Also, do you have control over the possible values for `country` and `device` fields? It looks like to me that the values come from a predefined set of values (maybe a drop down list in a web form?) If so, why not using `term` queries directly?

```
"country": {
"type": "string",
"index": "not_analyzed",
"doc_values": true
},
```
country and device are indeed lists, but there are more fields that are not predefined, with long list of values.
if i want to reindex, with new mapping, can i keep somehow the original values, and also have the ability to search case-insensitive search?

Yes, see [https://www.elastic.co/guide/en/elasticsearch/reference/2.1/\_multi\_fields.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.1/_multi_fields.html)

Yes, the feature has been renamed into `fields` 🙂 I linked to the breaking change page but the link to the document is: [https://www.elastic.co/guide/en/elasticsearch/reference/2.1/multi-fields.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.1/multi-fields.html)
