Briefly, this error occurs when a wildcard query is used in Elasticsearch and the query string is normalized. Normalization can cause issues as it may change the query string in a way that it no longer matches the intended documents. To resolve this issue, you can either avoid using wildcard queries or disable normalization for the fields that are being queried. Alternatively, you can use the keyword analyzer for the fields that are being queried, as it does not normalize the query string.
