问题 I have an amazon cloudsearch domain. The aim is to filter if the field 'language' exists. Not all objects have a language, and I want to have the ones which do have a language filtered, but the ones that do not have any language to also be returned. I want to filter with ( or language:'en' language:null ) However null cannot be passed within a string. Is this possible? If so how would it be done. 回答1: I looked elsewhere aswell, it seems : The simplest way to do that, is to set a default value

问题 I'm getting a AWS Error Code: SignatureDoesNotMatch, Status Code: 403 when trying to send a mail through Amazon SES.

问题 I am trying to create a UITableView where more rows loads automatically as I scroll to the bottom of the list. This is typically like the search function on the Amazon app for iPhone. It loads about 20 rows at a time and when I scroll to the end of the first 20, then the next 20 automatically load up. Once loaded, it remains in memory. I am not considering an option where the last row says "Load more items" like in the App store app. Here is what I am trying to achieve: My current app thread

问题 I know the whole design should be based on natural aggregates (documents), however I'm thinking to implement a separate table for localisations (lang, key, text) and then use keys in other tables. However, I was unable to find any example on doing this. Any pointers might be helpful! 回答1: You are correct, DynamoDB is not designed as a relational database and does not support join operations.

问题 I am creating HITs on MTurk Sandbox using JAVA API. I am able to create HITs and also work on it by searching through worker UI. But those hits are not showing up in the "Manage" tab of the requester UI. 回答1: So as to interact with my own MTurk tasks I have developed a rudimentary management console to monitor, review, manage, and download data from API-launched tasks. The management console is entirely JavaScript based and runs locally in your web browser. It replicates most of the basic
