I am very new to MongoDB and its Java... SDK? Api? I have a very simple question, but I haven't been able to find a satisfactory answer.Let's say I have a collection of instances that are like:\[code\]{ "_id": { "$oid": "5156171e5d451c136236e738" }, "_types": [ "Sample" ], "last_z": { "$date": "2012-12-30T09:12:12.250Z" }, "last": { "$date": "2012-12-30T04:12:12.250Z" }, "section": "5156171e5d451c136236e70f", "s_mac": "AA:AA:AA:AA:AA:AA", "_cls": "Sample",}\[/code\]And I have a hard-coded Java list:\[code\]static List<String> MAC_LIST = Arrays.asList("90:27:E4:0E:3D2", "A8:269:E6:1D:8B");\[/code\]What I would like to know is how to query the MongoDB so it will give me all the objects whose \[code\]s_mac\[/code\] field has a value that appears in the \[code\]MAC_LIST\[/code\] List.I'm guessing I should use the $in operator, but I don't know how to translate it to Java code.Any hint or link to pages with explanations of the use of the \[code\]$in\[/code\] operator through the Java SDK would be appreciated!Thank you in advance
