Describe the bug:
KQL seems to silently remove leading zeros causing queries to fail.
When querying "customer: 00123" with Lucene we get results but KQL removes the leading zeros:
"filter":[{"bool":{"should":[{"match":{"customer":12282650}}]...
Lucene Query generates:
{"bool":{"must":[{"query_string":{"query":"customer: 0012282650","analyze_wildcard":true,"time_zone"...
Field type customer is keyword.
