When analyzing alpha+beta delta, I want the outcome of tokens to be `[ALPHA+BETA DELTA, ALPHABETADELTA, ALPHA, BETA, DELTA, ALPHA+, ALPHA+BETA]`. My anlyzer gives me the results that I am looking for, except for `[ALPHA+, ALPHA+BETA]`. How can I include them?

```
{
  "index": {
    "number_of_shards": 1,
    "analysis": {
      "filter": {
        "word_joiner": {
          "type": "word_delimiter",
          "catenate_all": true,
          "preserve_original": "true"
        }
      },
      "analyzer": {
        "word_join_analyzer": {
          "type": "custom",
          "filter": [
            "word_joiner",
            "uppercase"
          ],
          "tokenizer": "keyword"
        }
      }
    }
  }
}
```

I'm not certain the `word_delimiter` token filter can do what you need. You probably need something more involved. Especially, I don't see how you could get the `ALPHA+` part using `word_delimiter`.

But how can I get the other tokens without using it?
