Hello Everyone,

I have a MySQL database with a table that contains 2 importants fields **title** and **age\_range**.

That table saves documents like this `45;60` for documents designed for users between 45 and 60 years old, `18;70` for users between 18 and 70 years old and so on...

Now I would like to fire the query `test` on the field **title** with the filter `18;50` for the field **age\_range** that will return all documents matching `test` with the age range field contained in this interval including the 2 the 2 cases above for example.

For instance, I use Logstash to index my data.  
How can I achieve this?  
Any treatment to do while indexing my data with logstash?  
Any filter, tokenizer to use while indexing using ES analyzer?

Thank you in advance

No need to transform the data before it gets indexed in elasticsearch.

As for mapping, I'd recommend using [Range datatype](https://www.elastic.co/guide/en/elasticsearch/reference/current/range.html) which is designed for that kind of use case IMO.

I'd do something like:

```auto
PUT range_index
{
  "mappings": {
    "my_type": {
      "properties": {
        "age": {
          "type": "integer_range"
        }
      }
    }
  }
}

PUT range_index/my_type/1
{
  "title": "whatever",
  "age" : { 
    "gte" : 45,
    "lte" : 60
  }
}
PUT range_index/my_type/1
{
  "title": "whatever",
  "age" : { 
    "gte" : 18,
    "lte" : 70
  }
}

```

Then search with something like:

```auto
POST range_index/_search
{
  "query" : {
    "range" : {
      "age" : { 
        "gte" : 18,
        "lte" : 50 
      }
    }
  }
}

```

But again, you need to parse your documents before indexing them.  
You can use a grok filter in logstash or use ingest grok processor in elasticsearch directly.

Thank you for your quick response @dadoonet .

But it seams the answer you provided is for integer fields? or maybe am I wrong?  
Because as I said the ages are saved in a string field (MySQL varchar) in this format `'bottom_age;top_age'` for each row.

Yes. This is why I said that:
