ES cannot search for special characters when using wildcard search


We are using query_string for a quick search but looks like does not correctly work.

For instance I can find results using:

    "query": {
        "query_string": {
            "query": "oleg$",
            "fields": [
            "minimum_should_match": "100%"
    "size": 10

But when I try to use *leg$ ES doesn't return results.

Did anyone face this issue before? or can help?

Thank in advacne

Thanks in advance.
