The text query that you are using has been deprecated (effectively renamed) a while ago in favour of the match query. The match query supports a single field, but you can use the multi_match query which supports the very same options and allows to search on multiple fields. Here is an example that should be helpful to you:

{
    "query" : {
        "multi_match" : {
            "fields" : ["title", "subtitle"],
            "query" : "trying out ela",
            "type" : "phrase_prefix"
        }
    }
}

You can achieve the same using the Java API like this:

QueryBuilders.multiMatchQuery("trying out ela", "title", "subtitle")
    .type(MatchQueryBuilder.Type.PHRASE_PREFIX);
