使用AEM查询生成器检索父节点

Question

我需要使用AEM查询生成器检索父节点。

例如，这是我的问题：

path:/content/test/us/bar
1_property:product
1_property.operation:exists

2_property:product
2_property.value:8003170008212

此查询允许我检索以下元素：

1) /content/test/us/bar/table/jcr:content/releated/product/2  
2) /content/test/us/bar/chair/jcr:content/releated/product/1

使用此查询，可以检索放置在 /content/test/us/bar下的所有元素，这些元素包含8003170008212作为产品属性的值。

从前面的项目符号开始，我只需要返回父节点，例如：

1) /content/test/us/bar/table
2) /content/test/us/bar/chair

我可以通过编程实现我的目标，迭代结果并使用3次getParent（）方法。

我想知道：有没有一种方法可以通过查询生成器获得它？

Answer 1

如果搜索的属性始终存在于已知路径中，则可以将查询重写为

path=/content/test/us/bar
1_property=jcr:content/related/product
1_property.operation=exists

2_property=jcr:content/related/product
2_property.value=8003170008212 

这将导致

/content/test/us/bar/table
/content/test/us/bar/chair

这避免了在结果中循环并查找父节点。

例如，我的本地环境中的以下查询

path=/content/we-retail/language-masters/en
1_property=displayMode
1_property.operation=exists

2_property=displayMode
2_property.value=singleText

结果

/content/we-retail/language-masters/en/experience/wester-australia-by-camper-van/jcr:content/root/responsivegrid/contentfragment
/content/we-retail/language-masters/en/experience/arctic-surfing-in-lofoten/jcr:content/root/responsivegrid/contentfragment
/content/we-retail/language-masters/en/experience/steelhead-and-spines-in-alaska/jcr:content/root/responsivegrid/contentfragment
/content/we-retail/language-masters/en/experience/hours-of-wilderness/jcr:content/root/responsivegrid/contentfragment
/content/we-retail/language-masters/en/experience/skitouring/jcr:content/root/responsivegrid/contentfragment
/content/we-retail/language-masters/en/experience/fly-fishing-the-amazon/jcr:content/root/responsivegrid/contentfragment

但是将下面的查询重写为

path=/content/we-retail/language-masters/en
1_property=jcr:content/root/responsivegrid/contentfragment/displayMode
1_property.operation=exists

2_property=jcr:content/root/responsivegrid/contentfragment/displayMode
2_property.value=singleText

结果

/content/we-retail/language-masters/en/experience/wester-australia-by-camper-van
/content/we-retail/language-masters/en/experience/arctic-surfing-in-lofoten
/content/we-retail/language-masters/en/experience/steelhead-and-spines-in-alaska
/content/we-retail/language-masters/en/experience/hours-of-wilderness
/content/we-retail/language-masters/en/experience/skitouring
/content/we-retail/language-masters/en/experience/fly-fishing-the-amazon
