By default, AddSearch can work with any language. You can advance search language understanding by adding language-specific stemming.
AddSearch uses two methods to determine the language of a page. If you have a multilingual website and are seeing different languages mixed together in your search results, please review that you’re using either of these methods to tell AddSearch the language of the page:
Include the lang or xml:lang attribute in the HTML tag, as follows:
<html lang="es"> <html xml:lang="es">
Include a dc.language or content-language meta tag in the HEAD section of your page, as follows:
<meta name="dc.language" content="es" /> <meta http-equiv="content-language" content="es" />
The examples above set the language to Spanish.
Your PDF files need to have Language meta information in place. Go to Adobe’s instructions on how to set the Language.
