Hello 🙂
I can't figure out the problem at all. I have a field with a title. The name consists of a hyphen. This is: "usd-coin". I'm trying to search with this query:
```auto
{
"sort": [
{
"time": "desc"
}
],
"query": {
"bool": {
"must": [
{"term": {"currency": "usd-coin"}}
]
}
}
}
```
In the end, it doesn't look for anything. But as soon as I leave "usd" - everything will be found. I need search accuracy. Can you please tell me how I can search specifically for the query "usd-coin"?
As far as I understand, the hyphen is reserved by the system. But how can this be bypassed?
I will be grateful for the answers.

Use a keyword datatype instead.

Can you please tell me how to specify this?

As I understand it, you need to recreate the partition and specify the mappings. But I already have a table. How can I search in my case?

Yes. You need to reindex the data of you want to use the right mapping for your use case.
Here, as a workaround, you could maybe use a phrase query. Although this might work, be aware that it's a workaround and that you'd better use the right mapping.

You can try to create a runtime field with the `keyword` map for that specific field.
It would be something like this:
```auto
PUT your-index-name/
{
"mappings": {
"runtime": {
"currency": {
"type": "keyword"
}
}
}
}
```
Be aware that runtime fields can impact the search performance in some cases, the best solution would indeed be a reindex, but maybe the runtime field can solve your problem quickly.
You can read more about runtime fields in the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime.html).

OMG! I forgot about this one. Thanks @leandrojmp !
