How to filter including files for ember addon?

I try to create ember-addon

Addon's structure are ( created with ember-cli addon generator):

/index.js
/Brocfile.js
/addon
/addon/models
/addon/models/model1.js
/addon/models/model2.js
/package.json

And in my vendor.js i can find definition for model1.js and model2.js

How ( and where ) i can filter this files? For example include only model2.js and skip model1.js

I suppose that some logic can be created at Brocfile but i can't find any information
