I created an index called `my_index` by this command

```auto
{
    "settings": {
        "number_of_shards": 1,
        "analysis": {
            "filter": {
                "synonym": {
                    "type": "synonym",
                    "lenient": "true",
                    "synonyms": [
                        ...
                        ...
                        ...
                    ]
                }
            },
            "analyzer": {
                "synonym": {
                    "filter": [
                        "uppercase",
                        "synonym"
                    ],
                    "tokenizer": "whitespace"
                }
            }
        }
    },
    "mappings": {
        "items": {
            "properties": {
                "country": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                },
                "information": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    },
                    "analyzer": "synonym"
                },
                "person": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                }
            }
        }
    }
}

```

inside `information`, I had a data that looks like this `100 /INDIA/2022` (pay attention to the space after 100). If i search for `100/INDIA/2022` (no space after 100), Elasticsearch will return nothing. If I create new index with no analyzer, `100/INDIA/2022` will return the expected result. Can someone help me for this problem?

That's indeed because of the analyzer used.  
In the first example, your analyzer is using a whitespace tokenizer at index time and search time.

The second example uses a standard tokenizer.

Use the \_analyze API to understand how your text is transformed at index time **and** at search time.

If you can't find the same tokens, that explains why the search does not give any result.

I see. It seems that change the `tokenizer` into `standard` solved the problem. Thank you
