Add method to detect symbols like +, /, etc. in the queries

Description

Add some method to detect symbols in the query. Let us say, we want to know how to use + sign to concatenate two strings. To know this, one can pass queries, like

• howdoi use + concat strings
• howdoi use plus concat strings
• etc.

At present, the outputs for these two are as shown below:

> howdoi use + concat strings
+

> howdoi use plus concat strings
public class Concat {
    String cat(String a, String b) {
        a += b;
        return a;
    }
}

Additional Comments (if any)

Similarly, the results vary significantly for queries like howdoi a divide b, howdoi a / b, etc.
