Calcite-elasticsearch v1.36.0，How to use keyword LIKE/CONTAINS/Regex for match query in sql?

[侯宾宾]

Hello, everyone.

In calcite-elasticsearch v1.36.0，I wanna to query sth in es with match
query or wildcard query.

I try sql like 【SELECT * FROM booksmapping WHERE title like '%Java%'】

But failed:

```
Suppressed: java.lang.UnsupportedOperationException: LIKE not yet supported
at
org.apache.calcite.adapter.elasticsearch.PredicateAnalyzer$Visitor.binary(PredicateAnalyzer.java:377)
```

By the way, it seems CONTAINS also not support varchar type by default.

```java
private static void showContains(CalciteConnection calciteConnection) {
    try {
        String sql = "SELECT * FROM booksmapping WHERE title contains
'Java'";
        Statement statement = calciteConnection.createStatement();
        ResultSet resultSet = statement.executeQuery(sql);
        System.out.println(ResultSetUtil.resultString(resultSet));
    } catch (SQLException e) {
        throw new RuntimeException(e);
    }
}
```

error logs

```
