elasticsearch n-gram example clarification -

with reference example quoted here https://www.elastic.co/guide/en/elasticsearch/guide/current/ngrams-compound-words.html

looking "adler" returns results. search “adler” becomes query 3 terms adl, dle, , ler:

but why query "zdler" returning results though zdl not 1 of terms ?

get /my_index/my_type/_search {     "query": {         "match": {             "text": {             "query": "zdler"             }           }         } } 

applying match query search on "adler" returns record -- expected.

however, match query on "zdler" returns record (because dle , ler match). setting "minimum_should_match": "100%" returns record - not expected

applying term query search on "adler" returns nothing -- not expected

post /my_index/my_type/_search     {     "query": {         "term": {           "text": {             "value": "adler"           }         }       }     } 

how achieve returning record search on "adler" , not on "zdler" ?

 "settings": {   "index": {     "number_of_shards": "5",     "provided_name": "my_index",     "creation_date": "1501069624443",     "analysis": {       "filter": {         "trigrams_filter": {           "type": "ngram",           "min_gram": "3",           "max_gram": "3"         }       },       "analyzer": {         "trigrams": {           "filter": [             "lowercase",             "trigrams_filter"           ],           "type": "custom",           "tokenizer": "standard"         }       }     },     "number_of_replicas": "1",     "uuid": "z5bxi_rjtacztsr_-nu9tw",     "version": {       "created": "5040099"     }   } } 

and these mappings

{  "my_index": { "mappings": {   "my_type": {     "properties": {       "text": {         "type": "text",         "analyzer": "trigrams"       }     }   } } 

match query applies field analyzer on input query before throwing query. produces tokens input ("zdler") matched again inverted index. same not case terms query doesn't apply field analyzer on input value

match query breaks "adler" -> "a", "d", "l", "e" ..... on matched against inverted index.

try understand follow 2 queries

post index5/_search {   "query": {     "match": {       "text": "zdler"     }   } }   post index5/_search {   "query": {     "term": {       "text": {         "value": "zdler"       }     }   } }
