Acquia Search can index sites in most languages, but Acquia Search passes content through a language-specific stemmer during indexing, depending on the search schema you have set for your website. Acquia Search offers search schemas for Dutch, French, German, and Spanish, as well as English. This means languages other than the schema's language are likely to produce lower-quality search results because partial words, plurals and other variations may not be correctly indexed. You can still search in most languages, but the search results will not be as good as they would be with a language-specific schema.
To select a language-specific schema:
- On the Search page in the Acquia UI, click the gear icon.
- In ApacheSolr module version, select the version that matches your Drupal version and preferred language, then click Save. For example, for Dutch, select apachesolr 7.x-1.0+, Optimized for Dutch.
If your site is in a language other than English, Dutch, French, German, or Spanish, contact Acquia support to see whether a search schema specific to that language can be made available for you.
