How to highlight ngram tokens in a word using elastic search
The correct way to achieve what you want is using ngram as tokenizer and not filter. You can do something like this:
"analysis" : { "filter" : { "meeteor_stemmer" : { "name" : "english", "type" : "stemmer" } }, "tokenizer" : { "meeteor_ngram_tokenizer" : { "type" : "nGram", "min_gram" : "2", "max_gram" : "15" } }, "analyzer" : { "meeteor_search_term_analyzer" : { "filter" : [ "lowercase", "asciifolding" ], "tokenizer" : "standard" }, "meeteor_index_analyzer" : { "filter" : [ "lowercase", "asciifolding" ], "tokenizer" : "meeteor_ngram_tokenizer" }, "meeteor_project_id_analyzer" : { "tokenizer" : "standard" } }},It will generate the highlighting by ngram for you like this:
"...highlight" : { "name" : [ "Sad <em>Me</em>eting" ] }
