Looks good.

I wonder if we should also add the categories, tags and authors to the free text. Might be nice to be able to search for them.

[yakky]

Do we need to handle this in newsblog, or rather in aldryn-categories?

[intellectronica]

Not sure how you could do that in the categories app (with the result that you find blog posts, not categories).

[mikek]

@czpython can you, please, have a look this: what can be considered a generic enough to add to blog search index?

[czpython]

please use get_plugin_index_data since it has certain rules to know what to index, to keep consistent accross all apps, this function cleans the plugin data and returns a list that you can then use to extend the text_bits list.

[czpython]

categories, tags, authors should be added here, not in the categories app.

[yakky]

Thanks @czpython, will comply

@czpython probably we should change a bit aldryn_search to better support parler. See https://github.com/aldryn/aldryn-newsblog/blob/feature/search_index/aldryn_newsblog/search_indexes.py#L24

parler requires the use of qs.translated instead of qs.filter
