Its not searching the contains and postfix string.

[atindersingh67]

I am using reactive search . Its searching the text with prefix only, but its not search text with postfix and contains.
For eg. i have description filed with the data 'product1 BN2445 with red color' if search for 'prod' , 'red' or 'color' its giving me results,
But if i search with '2445' its not giving me result,

My index creation code is below,
`POST /product2/product
{

"settings": {
"index": {
"analysis" : {
"analyzer":{
"autosuggest_analyzer": {
"filter": [
"lowercase",
"asciifolding",
"autosuggest_filter"
],
"tokenizer": "standard",
"type": "custom"
},
"ngram_analyzer": {
"filter": [
"lowercase",
"asciifolding",
"ngram_filter"
],
"tokenizer": "standard",
"type": "custom"
}
},
"filter": {
"autosuggest_filter": {
"max_gram": "7",
"min_gram": "1",
"token_chars": [
"letter",
"digit",
"punctuation",
"symbol"
],
"type": "edge_ngram"
},
"ngram_filter": {
"max_gram": "9",
"min_gram": "2",
"token_chars": [
"letter",
"digit",
"punctuation",
"symbol"
],
"type": "ngram"
}
}
},
"max_ngram_diff":"50"
}
},
"mappings" : {

    "properties" : {
      "@timestamp" : {
        "type" : "date"
      },
      "@version" : {
        "type" : "text",
        "fields" : {
          "keyword" : {
            "type" : "keyword",
            "ignore_above" : 256
          }
        }
      },
    
      "standardiseddescription" : {
        "type" : "text",
         "fields" : {
          "keyword" : {
            "type" : "keyword",
            "ignore_above" : 256
          }
        }
      }
    }
  }

}`

And my data search component is below

<DataSearch componentId="result" dataField = {[ "standardiseddescription" ]} fuzziness = {'AUTO'} size = {3} autosuggest={true} queryFormat="and" style = {{ marginBottom: 20 }} URLParams={true} />

I have already spend 3 days on this. Thanks in advance

You're doing an infix search over here, for doing this effectively, you need to use a n-gram analyzer.

 "standardiseddescription" : {
        "type" : "text",
         "fields" : {
          "keyword" : {
            "type" : "keyword",
            "ignore_above" : 256
          },
          "infix-search": {
            "analyzer": "ngram_analyzer"
          }
        }
      }

Now change the data field in your search to standardiseddescription.infix-search.
