ElasticSearch Multi Search query not return results - elasticsearch

Question

I am new to ElasticSearch and running version. 2.3.5.
I am running this query:
{
"query" : {
"multi_match" : {
"type" : "cross_fields",
"query" : "John Schmidt Sankt Boulevard 118b 2554 Island",
"minimum_should_match" : "50%",
"operator" : "and",
"fields" : ["*Name", "*Street.*hasStringValue", "*hasStreetNumber", "*hasPostCode", "*PostalLocality.*hasStringValue"]
}
}
}
However it does not return any result. If I remove the 'b' after 118 from the query from the query it returns the document.
All other fields is a match so how can I make ElasticSearch return the document?
Here is the mapping:
{
"my_index" : {
"mappings" : {
"datasubject" : {
"properties" : {
"#context" : {
"properties" : {
"con" : {
"type" : "string"
},
"cor" : {
"type" : "string"
},
"geo" : {
"type" : "string"
},
"per" : {
"type" : "string"
}
}
},
"cor:Person" : {
"properties" : {
"con:hasContactPoint" : {
"properties" : {
"con:Mobile" : {
"properties" : {
"con:hasAreaCode" : {
"type" : "string"
},
"con:hasCompleteTelephoneNumberString" : {
"type" : "string"
},
"con:hasCountryCode" : {
"type" : "string"
}
}
},
"con:PostalAddress" : {
"properties" : {
"con:hasAddressPoint" : {
"properties" : {
"geo:StreetAddress" : {
"properties" : {
"con:hasPostCode" : {
"type" : "string"
},
"con:hasPostalLocality" : {
"properties" : {
"geo:PostalLocality" : {
"properties" : {
"cor:hasStringValue" : {
"type" : "string"
}
}
}
}
},
"geo:hasStreet" : {
"properties" : {
"geo:Street" : {
"properties" : {
"cor:hasStringValue" : {
"type" : "string"
}
}
}
}
},
"geo:hasStreetNumber" : {
"type" : "string"
}
}
}
}
}
}
}
}
},
"cor:hasBirthDate" : {
"properties" : {
"cor:Date" : {
"properties" : {
"cor:hasDateValue" : {
"type" : "date",
"format" : "strict_date_optional_time||epoch_millis"
}
}
}
}
},
"cor:hasName" : {
"properties" : {
"per:Name" : {
"properties" : {
"per:familyName" : {
"type" : "string"
},
"per:givenName" : {
"type" : "string"
}
}
}
}
},
"cor:isIdentifiedBy" : {
"properties" : {
"cor:GEDIvA" : {
"properties" : {
"cor:hasCompleteIdentifierValue" : {
"type" : "string"
}
}
},
"dataset/pdi:IndividualId" : {
"properties" : {
"cor:hasCompleteIdentifierValue" : {
"type" : "string"
}
}
}
}
}
}
}
}
}
}
}
}
And here is the index settings:
