+Advanced Search Syntax
+======================
+
+Kanboard use a simple query language for advanced search.
+
+Example of query
+----------------
+
+This example will returns all tasks assigned to me with a due date for tomorrow and a title that contains "my title":
+
+```
+assigne:me due:tomorrow my title
+```
+
+Search by task id or title
+--------------------------
+
+- Search by task id: `#123`
+- Search by task id and task title: `123`
+- Search by task title: anything that don't match any search attributes
+
+Search by status
+----------------
+
+Attribute: **status**
+
+- Query to find open tasks: `status:open`
+- Query to find closed tasks: `status:closed`
+
+Search by assignee
+------------------
+
+Attribute: **assignee**
+
+- Query with the full name: `assignee:"Frederic Guillot"`
+- Query with the username: `assignee:fguillot`
+- Multiple assignee lookup: `assignee:user1 assignee:"John Doe"`
+- Query for unassigned tasks: `assignee:nobody`
+- Query for my assigned tasks: `assignee:me`
+
+Note: Kanboard will also search in assigned subtasks with the status todo and in progress.
+
+Search by color
+---------------
+
+Attribute: **color**
+
+- Query to search by color id: `color:blue`
+- Query to search by color name: `color:"Deep Orange"`
+
+Search by due date
+------------------
+
+Attribute: **due**
+
+- Search tasks due today: `due:today`
+- Search tasks due tomorrow: `due:tomorrow`
+- Search tasks due yesterday: `due:yesterday`
+- Search tasks due with the exact date: `due:2015-06-29`
+
+The date must use the ISO8601 format: **YYYY-MM-DD**.
+
+All string formats supported by the `strtotime()` function are supported, by example `next Thursday`, `-2 days`, `+2 months`, `tomorrow`, etc...
+
+Operators supported with a date:
+
+- Greater than: **due:>2015-06-29**
+- Lower than: **due:<2015-06-29**
+- Greater than or equal: **due:>=2015-06-29**
+- Lower than or equal: **due:<=2015-06-29**
+
+Search by modification date
+---------------------------
+
+Attribute: **modified** or **updated**
+
+The date formats are the same as the due date. 
+
+There is also a filter by recently modified tasks: `modified:recently`.
+
+This query will use the same value as the board highlight period configured in settings. 
+
+Search by creation date
+-----------------------
+
+Attribute: **created**
+
+Works in the same way as the modification date queries.
+
+Search by description
+---------------------
+
+Attribute: **description**
+
+Example: `description:"text search"`
+
+Search by external reference
+----------------------------
+
+The task reference is an external id of your task, by example a ticket number from another software.
+
+- Find tasks with a reference: `ref:1234` or `reference:TICKET-1234`
+
+Search by category
+------------------
+
+Attribute: **category**
+
+- Find tasks with a specific category: `category:"Feature Request"`
+- Find all tasks that have those categories: `category:"Bug" category:"Improvements"`
+- Find tasks with no category assigned: `category:none`
+
+Search by project
+-----------------
+
+Attribute: **project**
+
+- Find tasks by project name: `project:"My project name"`
