I can't find any whay to do it, saidly.
I will add a feature request on it

Theoratically it can be done as, but I am not sure. On top of that, not familiar with Elastic Search syntax also :(

string q = "ElasticSearchQueryToGetTheseDetails";
IQueriedSearch<ISearchContent> queriedSearch = SearchClient.Instance.UnifiedSearch(Language.None)
.For(q);
UnifiedSearchResults result = (queriedSearch).Take(20).GetResult(null, true);

I like it when it is simple :)

I added a request here: http://world.episerver.com/forum/developer-forum/Feature-requests/Thread-Container/2015/6/possible-to-get-information-about-most-frequent-searches-through-statistics-api-in-episerver-find/

+1, But what if i need that before version x.y.z :)

There is no way to do this through the API right now. Unified search can not be used since this statistics uses its own index. I think this might be added since it does seem to be a useful feature. For now, this can be achived using a rest request to the stats index like 

EPiServer/Find/proxy/_stats/query/top?from=2015-06-09T12%3A00%3A00Z&to=2015-06-10T12%3A00%3A00Z&interval=hour&size=25

which is what the Find UI does. The response would look like

{"status":"ok","total":1,"hits":[{"query":"alloy","count":1}]}

Thanks Viktor, that was great to know!
