I configure the Word Delimiter filter as follow:

> ```
> "type" : "word_delimiter",
> "generate_word_parts": "true",
> "split_on_numerics": "false",
> "split_on_case_change": "false",
> "preserve_original": "true"
> 
> ```

However, I notice that if I have the query "AEROSOL-GENERATING", it creates 2 tokens: AEROSOL and GENERATING. It will then retrieve documents with aerosol OR generating OR aerosol-generating. How can I change this behavior for the word parts from OR to AND? I.e. I want to run this query as ((aerosol AND generating) OR aerosol-generating).

Tips highly appreciated!
