DeprecationWarning: Chunk.modules is deprecated.

[c0defre4k]

In Webpack >= 3 this warning is thrown:

DeprecationWarning: Chunk.modules is deprecated. Use Chunk.getNumberOfModules/mapModules/forEachModule/containsModule instead.

In this case search.js's files method should use the Chunk.mapModules instead of Object.keys to get the same result.

Thank you very much @c0defre4k for the information, I updated the code to replace the deprecated property.
The warning should not appear anymore in v0.10.1.
