Tengo una matriz que contiene varias matrices, cada una con varios objetos, similar a esto.

[[object1, object2],[object1],[object1,object2,object3]]

Aquí hay una captura de pantalla del objeto registrado en la consola.

¿Cuál sería el mejor enfoque para aplanar esto, por lo que es solo una serie de objetos?

He intentado esto sin suerte:

console.log(searchData);  
  var m = [].concat.apply([],searchData);    
console.log(m);

searchData cierra la captura de pantalla anterior, pero m cierra la sesión []

Aquí está el contenido real de searchData:
