GET /bank/account/_search
{
"query" : {
"match_phrase" : {

}
},
"highlight": {
"pre_tags" : ["<tag1>"],
"post_tags" : ["</tag1>"],
"fields" : {
"address" : {}
}
}
}
with above query i get exact result what i needed, this is the result i got
highlight": {
"address": [
"990 <tag1>Mill</tag1> Road"
]
}
i tried the same query using php i am not get the highlighted results my php query is
<?php
require 'vendor/autoload.php';
$client=new Elasticsearch\Client();
$indexParams = [
