ElasticUtils exposes Elasticsearch More Like This API with the MLT class.
For example:
mlt = MLT(2034, index='addon_index', doctype='addon')
This creates an MLT that will return documents that are like document with id 2034 of type addon in the addon_index.
You can pass it an S instance and the MLT will derive the index, doctype, ElasticSearch object and also use the search specified by the S in the body of the More Like This request. This allows you to get documents like the one specified that also meet query and filter criteria. For example:
s = S().filter(product='firefox')
mlt = MLT(2034, s=s)
See elasticutils.MLT for more details.
