+  Scenario Outline: sharee searches files by content
+    Given using <dav-path-version> DAV path
+    And user "Brian" has been created with default attributes and without skeleton files
+    And user "Alice" has created folder "uploadFolder"
+    And user "Alice" has uploaded file with content "hello world from nepal" to "uploadFolder/keywordAtStart.txt"
+    And user "Alice" has uploaded file with content "saying hello to the world" to "uploadFolder/keywordAtMiddle.txt"
+    And user "Alice" has uploaded file with content "nepal want to say hello" to "uploadFolder/keywordAtLast.txt"
+    And user "Alice" has uploaded file with content "Namaste nepal" to "uploadFolder/hello.txt"
+    And user "Alice" has shared folder "/uploadFolder" with user "Brian"
+    And user "Brian" has accepted share "/uploadFolder" offered by user "Alice"
+    When user "Brian" searches for "Content:hello" using the WebDAV API
+    Then the HTTP status code should be "207"
+    And the search result of user "Brian" should contain only these files:
+      | keywordAtStart.txt  |
+      | keywordAtMiddle.txt |
+      | keywordAtLast.txt   |
+    Examples:
+      | dav-path-version |
+      | old              |
+      | new              |
