Question

I recreate the Search service application and the default Content source stayning in the 'Recovering' status.
The log give multiple error 'Unable to load word breaker for locale 0. Error code 8007007e.'
The default language is English and the reference in registry for word breaker dll is naturallanguage1.dll but I found only the naturallanguage6.dll.

Hi,
For your issue, check your current language settings and ensure that search supports the current language.
On the SharePoint Server open Registry Editor (Start -> type “Regedit” and hit enter). 
Point to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OfficeServer\14.0\Search\Setup\ContentIndexCommon\LanguageResources\Default\English
Under the registry key for each of the languages there is a value called StemmerDLLPath and WBDLLPathOverride
Updated the registry entry with NATURA~1.dll to NATURA~2.dll
Point to Start -> Administrative Tools -> Services, right click on SharePoint Server Search 14 and click on Restart.
Performed a Full Crawl and wait for the Full Crawl to complete and try searching again.
