Hello,

So essentially you simply want case-insensitive prefix search?

What was wrong with [my answer to your previous, similar question](https://discourse.hibernate.org/t/autocomplete-with-hibernate-search-6/5006/4)?

It should work similarly for an ID field. You will just have to declare new analyzers where you remove unnecessary analysis components, such as the tokenizer (replace it with a `KeywordTokenizer`) and the `SnowballPorterFilterFactory` (remove it, you don’t need it for IDs).

Alternatively, you can use a `@KeywordField` with a simple “lowercasing” normalizer (similar to the one named `lowercase` in [this example](https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#backend-lucene-analysis-analyzers)), and rely on a [wildcard predicate](https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#search-dsl-predicate-wildcard). It’s less flexible, but should work for simple use cases.
