+  Scenario Outline: search across files with different format
+    Given using <dav-path-version> DAV path
+    And the administrator has assigned the role "Space Admin" to user "Alice" using the Graph API
+    And user "Alice" has created a space "project-space" with the default quota using the GraphApi
+    And user "Alice" has uploaded file with content "this is a simple text file" to "test-text-file.txt"
+    And user "Alice" has uploaded file with content "this is a simple pdf file" to "test-pdf-file.pdf"
+    And user "Alice" has uploaded file with content "this is a simple cpp file" to "test-cpp-file.cpp"
+    And user "Alice" has uploaded file with content "this is another text file" to "testfile.txt"
+    And user "Alice" has uploaded file "filesForUpload/testavatar.png" to "/testavatar.png"
+    And user "Alice" has uploaded a file inside space "project-space" with content "this is a simple markdown file" to "test-md-file.md"
+    And user "Alice" has uploaded a file inside space "project-space" with content "this is a simple odt file" to "test-odt-file.odt"
+    When user "Alice" searches for "Content:simple" using the WebDAV API
+    Then the HTTP status code should be "207"
+    And the search result of user "Alice" should contain these entries:
+      | test-text-file.txt |
+      | test-pdf-file.pdf |
+      | test-cpp-file.cpp |
+      | test-md-file.md   |
+      | test-odt-file.odt |
+    But the search result of user "Alice" should not contain these entries:
+      | testavatar.png |
+      | testfile.txt   |
+    Examples:
+      | dav-path-version |
+      | old              |
+      | new              |
+      | spaces           |
