More Like This API
editMore Like This API
editThe more like this (mlt) API allows to get documents that are "like" a specified document. Here is an example:
$ curl -XGET 'http://localhost:9200/twitter/tweet/1/_mlt?mlt_fields=tag,content&min_doc_freq=1'
The API simply results in executing a search request with
moreLikeThis query (http
parameters match the parameters to the more_like_this query). This
means that the body of the request can optionally include all the
request body options in the search
API (facets, from/to and so on).
Rest parameters relating to search are also allowed, including
search_type, search_indices, search_types, search_scroll,
search_size and search_from.
When no mlt_fields are specified, all the fields of the document will
be used in the more_like_this query generated.
Note: In order to use the mlt feature a mlt_field needs to be either
be stored, store term_vector or source needs to be enabled.
