No need to fork Haystack, you can update that method in your own backend (for more details, see Stretching Haystack’s ElasticSearch Backend). The build_search_kwargs
method returns a dictionary so you can just modify the original return value.
Disclaimer: this code is just an example of how you could update your own backend, not how to implement fuzzy search.
class FuzzyBackend(ElasticsearchSearchBackend):
def build_search_kwargs(self, query_string, **kwargs):
fuzzy = kwargs.pop('fuzzy', False)
fuzzy_field = kwargs.pop('min_similarity', '')
search_kwargs = super(FuzzyBackend, self).build_search_kwargs(
query_string, kwargs)
if fuzzy:
search_kwargs = {'fuzzy': {fuzzy_field: query_string}}
return search_kwargs
