Elastic query DSL: Wildcards in terms filter?

Question

I am trying to filter the documents using terms filter. I am not sure how to introduce wildcards in filter. I tried something like this:

\"filter\":{
  \"bool\":         


        

Answer 1

The terms filter doesn't support wildcards, queries do, though. Try this query instead

{
  "query": {
    "bool": {
      "must": {
        "wildcard": {
          "aircraft": "a380*"
        }
      }
    }
  }
}

Or if you absolutely need to use filters, you can try the regexp filter, too:

{
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": {
            "regexp": {
              "aircraft": "a380.*"
            }
          }
        }
      }
    }
  }
}

UPDATE:

In latest ES versions, use the following query instead since filtered has been removed:

{
  "query": {
    "bool": {
      "filter": {
         "regexp": {
           "aircraft": "a380.*"
         }
      }
    }
  }
}
