All nodes with a specific name
```sql
SELECT * FROM [nt:unstructured] AS node
WHERE ISDESCENDANTNODE(node, "/search/in/path")
AND NAME() = "nodeName"
```

All pages below content path
```sql
SELECT * FROM [cq:Page] AS page
WHERE ISDESCENDANTNODE(page ,"/search/in/path")
```

All components of a specific type
```sql
SELECT * FROM [nt:unstructured] AS comp
WHERE ISDESCENDANTNODE(comp, "/search/in/path")
AND [sling:resourceType] = "componentType"
```

All nodes where a property contains some String
```sql
SELECT * FROM [nt:unstructured] AS node
WHERE ISDESCENDANTNODE(node, "/search/in/path")
AND CONTAINS([propertyName], "someString")
```

Date property of child node is greater than
```sql
SELECT page.* FROM [cq:Page] AS page
INNER JOIN [nt:base] AS jcrcontent ON ISCHILDNODE(jcrcontent, page)
WHERE ISDESCENDANTNODE(page, "/content/path/to/page")
AND jcrcontent.[cq:lastModified] >= CAST("2015-06-02T00:00:00.000Z" AS DATE)
```

Every page with specific name
```sql
SELECT * FROM [cq:Page] AS page
WHERE ISDESCENDANTNODE(page, "/search/in/path")
AND name() = "pageName"
```

**XPATH**

Property not empty
```
/jcr:root/content/path/to/page//nodeName[@propertyName != ""]
```

Specific property contains
```
/jcr:root/content/path/to/page//nodeName[jcr:contains(@propertyName,'someValue')]
```

Any property contains
```
/jcr:root/content/path/to/page//*[jcr:contains(., 'someValue')]
```

AND operation (for more than one property)
```
/jcr:root/content/path/to/page//*[@firstPropertyName = "someValue", @secondPropertyName != "anotherValue"]
```

Get all jcr:content nodes that
* have a specific resourceType
* have any property that contains a specific (text-) value
* have a "grandchild" node, which has a specific resourceType
* have a "grandchild" node, which has a property called "date" greater than "2012-06-01" and less than "2016-07-01"
and order the result by the date property in descending order.
