Query String query is not accepting analyzer which defined in settings

Elastic Stack Elasticsearch

Hi Team,

I kept the following settings for an index facebook..

PUT /facebook
{
"settings" : {
"analysis": {
"analyzer": {
"wordAnalyzer": {
"type": "custom",
"tokenizer": "whitespace",
"filter": [
"word_delimiter_for_phone"
]
}
},
"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
}
}
}
},
"mapping":{
"face": {
"properties": {
"id": {
"type": "string"
},
"name": {
"type": "string"
}
}
}
}
}

I would like to retrieve the data by preserving the special characters in
the search term as it is, which is having special characters like -, /, ( ,
) ,
for this I have used the above analyzer and filter settings.

When am using query :

GET facebook/face/_search
{
"query": {

  "bool": {
      "must": [
         {
             "query_string": {
                "fields": [
                   "id","name"
                ],
                "query": "a/",
                "analyzer":"wordAnalyzer"
             }
         }
      ]
  }

}

}

Showing error as:

"error": "SearchPhaseExecutionException[Failed to execute phase [query],
all shards failed; shardFailures {[0IYtu1aLQ2qxfwLnbCFTHg][facebook][0]:
SearchParseException[[facebook][0]: from[-1],size[-1]: Parse Failure
[Failed to parse source ....................................

I would like to preserve the special characters while searching how can I
achieve this? do I need to change my query (or ) may I get any query to
search the term in different fields by preserving the special characters.
