Semantic search with NLP and elasticsearch

I am experimenting with elasticsearch as a search server and my task is to build a "semantic" search functionality. From a short text phrase like "I have a burst pipe" the system should infer that the user is searching for a plumber and return all plumbers indexed in elasticsearch.

Can that be done directly in a search server like elasticsearch or do I have to use a natural language processing (NLP) tool like e.g. Maui Indexer. What is the exact terminology for my task at hand, text classification? Though the given text is very short as it is a search phrase.
