= Search
The search looks up full words in //Tasknames (name)// and //Taskdescriptions (description)// without giving \
special search commands in the search string. The search will result in a tasklist.


=== Task search fields
* task_id (NUMERIC):
* assigned_user (TEXT):
* assigned_user_missing (BOOLEAN):
* name (TEXT):
* description (TEXT):
* state (TEXT):
** The state of a Task. It is one of the following states: Open, Finished, Closed, Cancelled
* targetdate (DATETIME):

=== Project related fields
* project_id (NUMERIC):
* project_name (TEXT):
* project_description (TEXT):

=== Comment related field
* comment (TEXT):


== Search syntax (Whoosh)
=== Logic operators
* AND
** **Example:** "foo AND bar" - Search will find all items with foo and bar.
* OR
** **Example:** "foo OR bar" - Search will find all items with foo, bar or with foo and bar.
* NOT
** **Example:** "foo NOT bar" - Search will find all items with foo and no bar.
=== Search in specific fields
A search pattern like //foo:bar// does look for //bar// in the field named //foo//.

This search pattern can also be combined with other search text via logical operators.
=== Search for specific content
* **Wildcards:**
* **Range:**
** From To:
** Above:
** Below:
* **Named constants:**
** //now//: Current date
** //-[num]y//: Current date minus [num] years
** //+[num]mo//: Current date plus [num] months
** //-[num]d//: Current date minus [num] days
** ...

== Examples
* [[/patt/tasklist/search?q=project_id:1|project_id:1]] gives results with all tasks of project number #1.
* [[/patt/tasklist/search?q=project_id:1 AND assigned_user:dirk|project_id:1 AND assigned_user:dirk]] gives results with all tasks of project number #1 which are assigned to 'dirk'.
* [[/patt/tasklist/search?q=assigned_user:dirk+AND+targetdate:[2000+to+%2b5d]|assigned_user:dirk AND targetdate:[2000 to +5d] ]] gives results with tasks having a targetdate within the next 5 days and assigned to 'dirk'.
