According to the attu release notes, it says that scalar field inverted indexing, which has been supported since Milvus 2.4, is supported in attu. However, as shown in the attached picture, it seems that only marisa-trie indexing is possible. Could you please verify this?

@shanghaikid thank you for your works! could you check this please?? 🙇
