Exact match in elastic search query : <p>I want to exactly match the string <code>":Feed:"</code> in a <code>message</code>  field and go back a day pull all such records. The json I have seems to also match the plain word <code>" feed "</code>. I am not sure where I am going wrong. Do I need to add <code>"constant_score"</code> to this query JSON? The JSON I have currently is as shown below:</p>

<pre><code>{
    "query": {
        "bool": {
            "must": {
                "query_string": {
                    "fields": ["message"],
                    "query": "\\:Feed\\:"
                }
            },
            "must": {
                "range": {
                    "timestamp": {
                        "gte": "now-1d",
                        "lte": "now"
                    }
                }
            }
        }
    }
}
</code></pre>
