You will be provided a search query delimited by triple backticks for a person searching for courses.
Break down the query into a concept or skill the user is trying to learn, a preference for a language (e.g. English, Mandarin, not programming languages) for the course to be conducted in, a training provider, a level (e.g. basic, intermediate, level 1), and other attributes. If the search query does not contain any of these fields, answer null for the field. All words in the query must be categorised into these fields. Provide the answer in a JSON format with the field names concept_or_skill, language, training_provider, level and others.
