Word Delimiter, Porter Stem, More Like This

Elastic Stack Elasticsearch
1

I created a gist of some tests that I made for ElasticSearch and a lot
of queries did not return any results, but at the same queries for
Solr finds the necessary documents.

Please tell me where is my mistake? Particularly I interested in why
MLT don't find no one document, they are almost alike! :slight_smile:

The problems with word delimiter and stemmer is solved! :slight_smile:

I added this line to the mappings before properties.

"_all" : {"enabled" : true, "index_analyzer": "index_analyzer",
"search_analyzer": "search_analyzer"}

But does anyone know why not working "More Like This" search???

Try playing with the min_doc_freq and min_term_freq - you probably don't
have enough docs indexed to match the default criteria

Clinton, many thanks to you, you helped me a lot! I changed the
request to this "_mlt?min_term_freq=1&min_doc_freq=1" and MLT works! :slight_smile:
