There're two solutions. The first one is EvernoteSearchWithAppleScript.lbaction. It just works if you have Evernote.app but not as fas as the second script.
The another one is my experiment to make my own searching. I've decided to found an easy way to search Evernote's notes through LaunchBar. Sadly this solution has 2 steps. In the first you should run Evernote Export to export all Evernote's notes to /Users/<userName>/Library/Group Containers/<Number>.com.evernote.Evernote/Evernote/evernoteExport
To search through the exported notes you should run Evernote Search. It's useful for me. I hope for anybody else too.
To install them, go to the github address above, click "Download ZIP" on the right side and double click the *.lbaction file you want to install.
