We have this code

void build(boolean isCustomer, int service, int fee) {
        
    if(isCustomer)
        service = service * -1;
        
    //  rest of the code
}

We wanted to find out whether there are any such scenarios where we are multiplying a value with -1, so we did a file search with * -1 and it listed out some other files

I believe with the asterisk any line ending with * -1 will be fetched, we can change our code to service *= -1; but is there a way to search for this exact occurrence of * -1? We even tried making Whole word and Case sensitive as true!
