如何使用Haystack / Whoosh在Django中使用下划线索引字符串

Question

I am trying to implement search with Haystack and Whoosh in a Django project.

The CharField I am trying to index has data like something_like_this . But it won't show up in the search result if I search for 'something' or 'this. It only works if I search for 'something_like_this'. Is there anyway to search the keywords in the CharFiled ?

All I can think of is to create another CharField , store the string without underscore of the original string and then index it. But that seems like stupid idea.

Make data_field a MultiValueField and implement the prepare_data_field method where you could do something like this:

prepare_data_field(self, obj):
    return obj.data_field.split('_')
