===== Search Engine =====

User can search all available charts through a simple and easy to use search engine. 
In the first tab 'Graph', on top of the page there is a search field. In this field user can type strings that will be used to find charts.

By default all words in that strings will be searched inside the device name, site, network, all custom fields, chart description, and all additional tags added to the device and to the chart itself.

Each word inserted in the search field will be searched in AND beaviour (all the words must be matched in almost a field). The comparison is by default case insensitive. Users can use these special flag in order to modify the default behavior:

  * **-case** the following word will be searched case sensitive
  * **-re** the following word represents a regular expression
  * **-no** the following word must not be included (case insensitive)
  * **-nocase** the following word must not be included (case sensitive)
  * **-nore** the following word represents a regular expression that must not be included
  * **id=X** force the search to specific charts. X is a comma sepatated list of chart ids
  * **device=X** force the search to specific devices. X is a comma separated list of device names.
