[Tracker] Search a Phrase

[Habib Seifzadeh <habibseifzadeh yahoo com>]

Hi guys,
First of all, thank you so much for the great tool.

My question is that how can I search a phrase using tracker? If for example I search "Syntax Tree", tracker 
finds any file including "Syntax" or "Tree" but it don't show files including exactly "Syntax Tree" phrase.

Is there any way for meeting my requirement or it has not been implemented yet?

Sincerely,
Habib Seifzadeh
