Limit the number of ElasticSearch outputs

I have this code; that can successfully do an ElasticSearch.

es = Elasticsearch()
index_name = 'db'
query_param = Q('bool', must = [Q('match_phrase', doc_text='electronic')])
search = Search(using=es, index="db").query(query_param)
result = search.execute()

The problem; when i print result, it only prints the top 10 hits (even though I know there are >500,000 entries in the db).

I've read the solution should be to use the 'size' parameter/or from and size. However, no matter where I insert 'size':50 into this code, or from and size parameters, I still can't change the number of outputs returned.

Could someone show me where in the code I can change the number of outputs returned? I want to limit the number based on the number of hits, not by kb or time or anything like that.

Thanks

So it turns out the answer is really simple, posting it here in case it helps anyone else (see the line where I've added in [0:50]).

    es = Elasticsearch()
    index_name = 'db'
    query_param = Q('bool', must = [Q('match_phrase', doc_text='electronic')])
    search = Search(using=es, index="db").query(query_param)[0:50]
    result = search.execute()

Look at this Elasticsearch python API, you have from_ and size parameters to perform your request.
