@AutoComplete in Redis OM Spring maps to Redis Query Engine suggestion dictionaries (backed by FT.SUGADD/FT.SUGGET).

Each @AutoComplete field = one dictionary.

So in your entity, code and name create two separate dictionaries.

Redis Query Engine itself can’t query two suggestion dictionaries in one call — you either:

• Merge them at query time, or
• Pre-combine fields into one @AutoComplete field.

For merging at query time:

@GetMapping("/search")
fun query(@RequestParam("q") query: String): List<Suggestion> {
    val codeResults = repository.autoCompleteCode(query, AutoCompleteOptions.get().withPayload())
    val nameResults = repository.autoCompleteName(query, AutoCompleteOptions.get().withPayload())

    return (codeResults + nameResults).distinctBy { it.string } // removes duplicates
}

If you want only one dictionary, store the values of name and code in a single @AutoComplete field instead.
