elasticsearch - How to create and add custom analyser in Elastic search? -

i have batch of "smartphones" products in es , need query them using "smart phone" text. m looking compound word token filter. , m planning use custom filter this:

curl -xput 'localhost:9200/_all/_settings -d ' {   "analysis" : {     "analyzer":{       "second":{         "type":"custom",         "tokenizer":"standard",         "filter":["myfilter"]       }       "filter": {         "myfilter" :{              "type" : "dictionary_decompounder"              "word_list": ["smart", "phone"]              }              }                  } } } ' 

is correct approach ? d ask how can create , add custom analyser es? looked several links couldn't figure out how it. guess m looking correct syntax. thank you

edit

i m running 1.4.5 version. , verified custom analyser added successfully:

{   "test_index" : {     "settings" : {       "index" : {         "creation_date" : "1453761455612",         "analysis" : {           "filter" : {             "myfilter" : {               "type" : "dictionary_decompounder",               "word_list" : [ "smart", "phone" ]             }           },           "analyzer" : {             "second" : {               "type" : "custom",               "filter" : [ "lowercase", "myfilter" ],               "tokenizer" : "standard"             }           }         },         "number_of_shards" : "5",         "number_of_replicas" : "1",         "version" : {           "created" : "1040599"         },         "uuid" : "xookedmbr260dnwygn_zqa"       }     }   } } 

your approach looks good, consider adding lowercase token filter, smartphone (notice uppercase 's') split smart , phone.

then create index analyzer this,

curl -xput 'localhost:9200/your_index -d ' {   "settings": {     "analysis": {       "analyzer": {         "second": {           "type": "custom",           "tokenizer": "standard",           "filter": [             "lowercase",             "myfilter"           ]         }       },       "filter": {         "myfilter": {           "type": "dictionary_decompounder",           "word_list": [             "smart",             "phone"           ]         }       }     }   },   "mappings": {     "my_type": {       "properties": {         "name": {           "type": "string",           "analyzer": "second"         }       }     }   } } ' 

here creating index named your_index, custom analyzer named second , applied name field.

you can check if analyzer working expected analyze api this

curl -xget 'localhost:9200/your_index/_analyze' -d ' {   "analyzer" : "second",   "text : "lg android smartphone" }' 

hope helps!!
