 #### Complex Documents
 
+You need to follow 2 rules for your documents:
+
+1. The document cannot start with an Array at the root index. This will introduce sequential data and isn't supported yet. See below for a workaround for such data.
+
+```js
+[ // <-- not allowed as document start!
+  {
+    "id": 0,
+    "title": "title"
+  }
+]
+```
+
+2. The id can't be nested inside an array (also none of the parent fields can't be an array). This will introduce sequential data and isn't supported yet. See below for a workaround for such data.
+
+```js
+{
+  "records": [ // <-- not allowed when id lives inside!
+    {
+      "id": 0,
+      "title": "title"
+    }
+  ]
+}
+```
+
+Here an example for a supported complex document:
+
 ```json
-[
+{
+  "meta": {
+    "tag": "cat",
+    "id": 0
+  },
+  "contents": [
+    {
+      "body": {
+        "title": "some title",
+        "footer": "some text"
+      },
+      "keywords": ["some", "key", "words"]
+    },
+    {
+      "body": {
+        "title": "some title",
+        "footer": "some text"
+      },
+      "keywords": ["some", "key", "words"]
+    }
+  ]
+}
+```
+
+The corresponding document descriptor (when all fields should be indexed) looks like:
+
+```js
+const index = new Document({
+    key: "meta:id",
+    tag: "meta:tag",
+    doc: [
+        "contents[]:body:title",
+        "contents[]:body:footer",
+        "contents[]:keywords"
+    ]
+});
+```
+
+Again, when searching you have to use the same colon-separated-string from your field definition.
+
+```js
+index.search(query, { 
+    field: "contents[]:body:title"
+});
+```
+
+#### Not Supported Documents (Sequential Data)
+
+This example breaks both rules from above:
+
+```js
+[ // <-- not allowed as document start!
   {
     "tag": "cat",
-    "records": [
+    "records": [ // <-- not allowed when id lives inside!

-Please notice this complex structure has its records as nested array which also includes the `key`.

+function add(sequential_data){
 
-```js
-index.search(query, { 
-    field: "records[]:body:title"
+    for(let x = 0, data; x < sequential_data.length; x++){
+
+        data = sequential_data[x];
+
+        for(let y = 0, record; y < data.records.length; y++){
+
+            record = data.records[y];
+
+            index.add({
+                tag: data.tag,
+                id: record.id,
+                record: record
             });
+        }
+    }  
+}
+
+// now just use add() helper method as usual:
+
+add([{ 
+    
+    // sequential structured data
+    // take the data example above
+    
+}]);
 ```
 
+You can skip the first loop when your document data has just one index as the outer array.
+
 #### Join / Append Arrays
 
 On the complex example above, the field `keywords` is an array but here the markup did not have brackets like `keywords[]`. That will also detect the array but instead of appending each entry to a new context, the array will be joined into on large string and added to the index.
 
-The difference of both kinds of adding array contents is the relevance when searching. When adding each item from an array via append to its own context with the syntax `field[]`, then the relevance of the last entry concurrent with the first entry. When you left the brackets in the notation, it will join the array to one string. Here the first entry has the highest relevance, whereas the last entry has the lowest relevance.
+The difference of both kinds of adding array contents is the relevance when searching. When adding each item of an array via `append()` to its own context by using the syntax `field[]`, then the relevance of the last entry concurrent with the first entry. When you left the brackets in the notation, it will join the array to one whitespace-separated string. Here the first entry has the highest relevance, whereas the last entry has the lowest relevance.
 
 So assuming the keyword from the example above are pre-sorted by relevance to its popularity, then you want to keep this order (information of relevance). For this purpose do not add brackets to the notation. Otherwise, it would take the entries in a new scoring context (the old order is getting lost).
