search module in GR

Hello . The search module works great with questions in GB - en lang and with numbers, But in Greek lang dont find resalts.... Do you know why ?
Regards!

Do you add Greek as a content language in Joomla? Do you use multi language website? If yes, probably the active language is not greek when the search returns only english results.

Yes. All its ok . The default lang is GReek and i have set the greek lang but dont works in greek results.

Could you show me your website? Right now nothing comes to my mind but please try to run Smart Search indexer again » Smart Search quickstart guide - Joomla! Documentation

By indexer I mean :

Click on the Components -> Smart Search menu item.
Click on the Index button in the toolbar to start the indexer. This will cause a modal window to load with some indexer status information and a progress bar. Depending on the size of your site, this can take a few minutes to a few hours to complete. The indexer uses AJAX requests to complete the overall process in small chunks so as to avoid timeouts and memory problems. Indexing is complete when the progress bar disappears and you see a message indicating that it is now safe to close the modal window.
