TYPO3 Core

My site is bi-lingual -- Swiss German (default) and English (secondary). And hence has two search pages.

Searching content in the default language yield all results as expected. Searching content in the secondary language delivers no results in external files.

While analysing the table index_phash I learned that rows representing external files always have sys_language_id=0.

1. MULTILINGUAL CONTENT SUPPORT #
   config.linkVars = L
   config.sys_language_mode = content_fallback ; 1,0

1. Setup the Default Language: German (Schwitzerland)
   config.sys_language_uid = 0
   plugin.tx_indexedsearch._DEFAULT_PI_VARS.lang = 0
   config.language = de
   config.locale_all = de_CH
   config.htmlTag_langKey = de_CH
   config.htmlTag_setParams = xmlns="http://www.w3.org/1999/xhtml"
   xml:lang="de_CH" lang="de_CH"

1. This Sets Up English
   [globalVar = GP:L = 1]
   config.sys_language_uid = 1
   plugin.tx_indexedsearch._DEFAULT_PI_VARS.lang = 1
   config.language = en
   config.locale_all = en_US
   config.htmlTag_langKey = en
   xml:lang="en" lang="en"
