/**
* as_app_builder_search_translations:
* @app: an #AsApp
* @prefix: a prefix to search, e.g. "/usr"
* @min_percentage: minimum percentage to add language
* @flags: #AsAppBuilderFlags, e.g. %AS_APP_BUILDER_FLAG_USE_FALLBACKS
* @cancellable: a #GCancellable or %NULL
* @error: a #GError or %NULL
*
* Searches a prefix for languages, and using a heuristic adds <language>
* tags to the specified application.
*
* If there are no #AsTranslation objects set on the #AsApp then all domains
* are matched, which may include more languages than you intended to.
*
* @min_percentage sets the minimum percentage to add a language tag.
* The usual value would be 25% and any language less complete than
* this will not be added.
*
* The purpose of this functionality is to avoid blowing up the size
* of the AppStream metadata with a lot of extra data detailing
* languages with very few translated strings.
*
* Returns: %TRUE for success
*
* Since: 0.5.8
