Hi Thanks,
I resolved this issue,
In order to preserve the special characters and to search the query term in
multiple fields for exact match it is better to change the settings as shown
below.
Settings I updated:
PUT /my_index/_settings?pretty=true
{
"settings" : {
"analysis": {
"analyzer": {
"wordAnalyzer": {
"type": "custom",
"tokenizer": "whitespace",
"filter": [
"word_delimiter_for_phone","nGram_filter"
]
}
},
"filter": {
"word_delimiter_for_phone": {
"type": "word_delimiter",
"catenate_all": true,
"generate_number_parts ": false,
"split_on_case_change": false,
"generate_word_parts": false,
"split_on_numerics": false,
"preserve_original": true
},
"nGram_filter": {
"type": "nGram",
"min_gram": 1,
"max_gram": 20,
"token_chars": [
"letter"
]
}
}
}
}
}
Mapping settings:
{
“mappings”:{
"face" : {
"properties" : {
"{field-1}id" : {
"type" : "string",
"index_name" : "change",
"analyzer": "wordAnalyzer"
},
"{field-2}name" : {
"type" : "string",
"index_name" : "change",
"analyzer": "wordAnalyzer"
},
"{field-3}Year":
{
"type" : "string",
"index_name" : "change",
"analyzer": "wordAnalyzer"
},
"{field-4}Make":
{
"type" : "string",
"index_name" : "change",
"analyzer": "wordAnalyzer"
}
}
}
and the query we can use:
GET my_index/face/_search
{
"query": {
"match": {
"change":
{
"query": "A/T o",
"type": "phrase_prefix"
}
}
}
}
By this we can search for that term in all the fields. In order to search in
only single field we can give that field name in the place of "change" in
match query.
And for to change in mappings I am able to update the analyzers, but not the
index_name, for to add index_name I have deleted the index and again done
the mapping as above.
