Analyzer for SKUs in Elasticsearch

## Analyzer for SKUs

The analyzer below will strip out any of the items defined in the regex.  In this case i am removing -#_ and any whitespace.
You can adapt the regex as appropriate.  In this case the search WILL be case sensitive.  
As a keyword tokenizer is used, then the text will not be split into "words" .  


```
PUT my-index-000001
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer": {
          "tokenizer": "keyword",
          "char_filter": [
            "my_char_filter"
          ]
        }
      },
      "char_filter": {
        "my_char_filter": {
          "type": "pattern_replace",
          "pattern": "[#_.-]|\\s",
          "replacement": ""
        }
      }
    }
  }
}
```

You can simulate how the analyzer works by using the call below:
```
POST my-index-000001/_analyze
{
  "analyzer": "my_analyzer",
  "text": "Mysku123 456-789"
}
```
