Search engine?

Question

elasticsearch

Recently I needed a search with typos and so on. Installed elasticsearch. Out of the box, the search works well, but I couldn't manage to sort the result alphabetically. For example, there are phrases:

System of a down
My own system
System 27
Presystem
Systemode

I need the user to write "system" to get first of all the lines that begin with this word. Elasticsearch, by default, indexes each word in a phrase separately and gives the result not as I need. I tried to change the tokenizer and so on. Tried something like this:

{
    "settings": {
        "index": {
            "analysis": {
                "analyzer": {
                    "analyzer_startswith": {
                        "tokenizer": "keyword",
                        "filter": "lowercase"
                    }
                }
            }
        }
    },
    "mappings": {
        "test_index": {
            "properties": {
                "title": {
                    "search_analyzer": "analyzer_startswith",
                    "index_analyzer": "analyzer_startswith",
                    "type": "string"
                }
            }
        }
    }
}

And search with match_phrase_prefix. But in this case, the search with typos stops working. In general, as I just did not experiment, I could not set up such a simple thing. Elastik's documentation is terrible!
Tell me, how is it with other engines, such as sphinx or solr? Easier in terms of setup.
What engine are you using?
