How do I query using Wildcard

Elastic Stack Elasticsearch
3

The simplified query below works

GET contacts/_search
{
    "query": {
      "bool": {
        "should": [ 
          {"nested": {
            "path": "organisation",
            "query": {
              "bool": {
                "should": [
                    {"multi_match": {
                  "query": "te",
                  "fields": ["organisation.name"],
                  "type": "best_fields"
                }},
                {"nested": {
                  "path": "screenData",
                  "query": {
                    "multi_match": {
                      "query": "advertising",
                      "fields": ["screenData.valueString"],
                      "type": "best_fields"
                    }
                  }
                }}
                ]
              }
            }
          }
        }]
      } 
    }
}

but a wildcarded equivalent doesn't..

GET contacts/_search
{
    "query": {
      "bool": {
        "should": [ 
          {"nested": {
            "path": "organisation",
            "query": {
              "bool": {
                "should": [
                    {"multi_match": {
                  "query": "te",
                  "fields": ["organisation.name"],
                  "type": "best_fields"
                }},
                {"nested": {
                  "path": "screenData",
                  "query": {
                    "multi_match": {
                      "query": "advertis*",
                      "fields": ["screenData.valueString"],
                      "type": "best_fields"
                    }
                  }
                }}
                ]
              }
            }
          }
        }]
      } 
    }
}

I have the screenData.valueString field analysed with the english analyser but have tried standard and not_analysed with the same results: no records.
