You either need to increase the size parameter or sort the data differently. By default only 10 hits come back from a search query and it might well be the case that the first 10 documents being returned are all for user_id: 4161.

GET _msearch
{ "index": ["index1", "index2", "index3"]}
{"size": 100, "query": {"terms": {"user_id": [4161,4402] } }}

The terms query is an OR query, i.e. terms: [4161,4402] is equivalent to term: 4161 OR term: 4402.

Another way since you're using _msearch is to send one query per index, since you'll be returning more data, you might be lucky and get data for both users.

GET _msearch
{ "index": "index1"}
{"query": {"terms": {"user_id": [4161,4402] } }}
{ "index": "index2"}
{"query": {"terms": {"user_id": [4161,4402] } }}
{ "index": "index3"}
{"query": {"terms": {"user_id": [4161,4402] } }}
