Swashbuckle set manually operationId, multiple operations with same verb

Question

I need to know if it's possible to set up custom operationid, or a naming convention, I mean I know that operation filter can be overwritten the way how operationId is generated

https://azure.microsoft.com/en-us/documentation/articles/app-service-api-dotnet-swashbuckle-customize/

using Swashbuckle.Swagger;
using System.Web.Http.Description;

namespace Something
{
    public class MultipleOperationsWithSameVerbFilter : IOperationFilter
    {
        public void Apply(
            Operation operation,
            SchemaRegistry schemaRegistry,
            ApiDescription apiDescription)
        {
            if (operation.parameters != null)
            {
                operation.operationId += "By";
                foreach (var parm in operation.parameters)
                {
                    operation.operationId += string.Format("{0}",parm.name);
                }
            }
        }
    }
}

in SwaggerConfig.cs

 c.OperationFilter<MultipleOperationsWithSameVerbFilter>();

Now this is helpful transforming swagger description, check bellow:

All good, now I endup with another problem, example similar with may cases: on same controller I have two endpoints

• Post: /customer boddy: {email, location....}
• Post: /customer/search boddy: {a filter, whatever}

The example is not quite correct (last post should be a get) but still le assume that webapi cannot be changed (new controller for separation) for this particular case I will try to figure out a way to generate operationId diffrent for each action somehow, but my question is this:

Is it possible to decorate somehow the controller actions similar with [JsonIgnore] or with [Route("customer/delete")], to be explicit about the operationId.

EDIT This answer relates to Swashbuckle 5.6 and .NET Framework. Please read mwilson's answer for Swashbuckle and .NET Core

You can use the SwaggerOperationAttribute provided by Swashbuckle for that.

[SwaggerOperation("get")]
public IEnumerable<Contact> Get()
{
    ....
}

[SwaggerOperation("getById")]
public IEnumerable<Contact> Get(string id)
{
    ...
}

You can use that attribute to add tags and schemes to your operation as well by the way. Have a look at the source code
