Add custom properties to INDEXED_PROPERTIES

[codediodeio]

Enhancement. The ability to add custom properties to the index.

algolia:
  applicationID: 'ID'
  apiKey: 'Key'
  indexName: 'index'
  properties:
    - featured_image
    - something_else

Good idea 👍

Would not it be easier to index all the properties though? It would spare us the need to configure things out.

Indexing everything could work, but customization might be desirable in certain cases. I needed this feature for a project, so here's a pull request that has been tested #29

I just met this problem, and there is a link do not want to be indexed.

@lanpangzhi if I understand well, there is a post/page you would not like to index? I have not thought about that, that's a good idea.

Do you write specific metadata in your post/page already that could be used to put them aside from the indexing process?
