Question

我必须在“Artilce”实体上的快速查找搜索中注册一个插件。当用户在Article实体的快速查找文本框中输入任何内容时，我的插件执行并返回基于我们的业务逻辑过滤数据。 1.当我们发现使用快速查找时会发生什么事件。 2.触发此事件时会传递什么消息。

我已经尝试在RetrieveMultiple消息上注册插件，但是当我们在快速查找中点击搜索时，这不会被触发。

请帮忙。

Answer 1

我们在RetrieveMultiple上注册了一个插件。我们有业务需求来搜索记录，默认使用WildCard。

插件注册详情：

Message: RetrieveMultiple

Primary Entity:None

Secondary Entity:None

Pre-Operation

public const String QueryLiteral = "Query";
    public const String LIKE = "%";
    public void Execute(IServiceProvider serviceProvider)
    {
        String ParentEntity = String.Empty;
        String OriginalSearch = String.Empty;

        // Obtain the execution context from the service provider. 
        var ContextInstance = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
        // Get a reference to the Organization service. 
        IOrganizationService ServiceInstance =
            ((IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory))).
                CreateOrganizationService(ContextInstance.InitiatingUserId);
        // Critical Point here - NOTICE that the InputParameters Contains the word Query
        if (ContextInstance.Depth < 2 && ContextInstance.InputParameters.Contains(QueryLiteral) &&
               ContextInstance.InputParameters[QueryLiteral] is QueryExpression)
        {
            QueryExpression QueryPointer = (ContextInstance.InputParameters[QueryLiteral] as QueryExpression);
            //Verify the conversion worked as expected - if not, everything else is useless
            if (null != QueryPointer)
            {
                // Check if the request is coming from any Search View 
                // We know this b/c Criteria isn't null and the Filters Count > 1
                if (null != QueryPointer.Criteria && QueryPointer.Criteria.Filters.Count > 1)
                {
                    ParentEntity = ContextInstance.PrimaryEntityName;
                    OriginalSearch = QueryPointer.Criteria.Filters[1].Conditions[0].Values[0].ToString();
                    OriginalSearch = String.Format(CultureInfo.CurrentCulture,
                                     "{0}{1}", LIKE, OriginalSearch);
                }
                ConditionExpression NewCondition = null;
                FilterExpression NewFilter = null;
                if (null != QueryPointer.Criteria)
                {
                    //Change the default 'BeginsWith'Operator to 'Contains/Like' operator in the basic search query
                    foreach (FilterExpression FilterSet in QueryPointer.Criteria.Filters)
                    {
                        foreach (ConditionExpression ConditionSet in FilterSet.Conditions)
                        {
                            if (ConditionSet.Operator == ConditionOperator.Like)
                            {
                                if (OriginalSearch != "")
                                    ConditionSet.Values[0] = OriginalSearch;
                                else
                                {
                                    OriginalSearch = QueryPointer.Criteria.Filters[0].Conditions[0].Values[0].ToString();
                                    OriginalSearch = String.Format(CultureInfo.CurrentCulture,
                                                     "{0}{1}", LIKE, OriginalSearch);
                                    ConditionSet.Values[0] = OriginalSearch;

                                }
                            }
                        }
                    }
                }
            }
            ContextInstance.InputParameters[QueryLiteral] = QueryPointer;
        }
 }

我们已经向微软提出了一张票，以解决这种情况。他们提供的解决方案是修改数据库以生成消息插件注册工具中提供了 SearchByTitleKbArticleRequest 。

我目前还不记得我们针对这些消息更新了一个标志的表。

更新表后，我们可以根据消息注册插件

<强> SearchByTitleKbArticleRequest

然后触发了插件，我们修改了从那里返回的实体集合。
