Supply: Unexpected MPNs being returned

Modified on Wed, 13 Sep, 2023 at 1:00 PM

When searching or matching sometimes additional parts are found where the MPNs differ only by non-alphanumeric characters, such as - or ..

For example, consider a supMultiMatch query for the following MPN:

query MultiMatch {
  supMultiMatch(queries: {mpn: "ASV-18432MHZ-EJ-T", limit: 5}) {
    hits
    parts {
      mpn
    }
  }
}

This may return multiple MPNs such as ASV-18.432MHZ-EJ-T as well as ASV-1.8432MHZ-E-J-T (and others).

This behaviour is due to the way parts are "tokenized" for indexing in the elastic search engine.

If an exact character match is required, the client application should compare the resulting MPNs against the input and filter.
