我有一个从SlingAllMethodsServlet扩展的servlet，它使用QueryBuilder在我们的存储库中的路径中搜索图像。当我执行servlet时，QueryBuilder返回0结果，但是当我从CQ提供的querydebug.html运行相同的查询时，它返回预期的结果。
我已将com.day.cq.search的日志级别设置为DEBUG以尝试查找我的错误，但我在记录器中看到两次查询尝试的相同输出（除了servlet请求返回0结果）。以下是servlet调用的日志输出：

以下是来自querydebug.html的输出：

以下是在servlet中运行查询的代码：
Map<String,String> parms = new HashMap<String,String>();
parms.put("type", "dam:Asset" );
parms.put( "path", "/content/dam/nhhc/our-collections/photography" );
// This search is only for low-res images so use the DPI value to keep from returning high-res images
parms.put( "property", "jcr:content/metadata/dam:Physicalheightindpi" );
parms.put( "property.value", "96" );
if( nodeName != null && !nodeName.isEmpty() ) {
parms.put( "nodename", nodeName );
}
Query query = builder.createQuery( PredicateGroup.create( parms ), session );
从日志中我可以看到，为servlet和来自querydebug运行的查询都是相同的，所以我不知道为什么从运行中运行时我没有得到任何结果。 servlet的。任何建议或指示将不胜感激。
