I have a requirement when searching for a product name to also return a different product that will replace it in the future.

For example, when the user searches for "Product ABC", I also want to return "Product D E F Extraword" but not "Product D E F".

We tried to solve this using a synonym filter, which kind of works but also returns "Product ABC" when you search for "Product D E F" because we used a mapping like the following:

```auto
     "english_synonyms": {
            "type": "synonym",
            "expand": "false",
            "synonyms": [
                  "Product D E F=>Product ABC",
                  "Product D E F,Product ABC=>Product D E F"
            ]
      }

```

I tried to replace this with a synonym graph token filter

```auto
     "english_synonyms": {
            "type": "synonym_graph",
            "expand": "false",
            "lenient": "true",
            "synonyms": [
              "Product D E F Extraword=>Product ABC"
            ]
          }

```

Which meets the requirement for searching for "Product ABC". "Product ABC" and "Product D E F Extraword" is returned, however, when searching for "Product D E F" only "Product D E F" is returned, I assume because "Product D E F Extraword" is mapped as a multi word synonym to "Product ABC"

So my question is, is this the right use of synonyms?

I have a suspicion that I should be trying to solve this by adding additional fields to the "Product D E F Extraword" document such as "alternative\_name" and solving this with a search query instead. Is this a better approach? Or is there another clever technique for mapping one word to another that I am missing?

If it is the correct use of synonyms what is wrong with my configuration to achieve the requirements?
