     115=== Index ===
     116One index by language is created and specific language analyzer could be define (eg. FrenchAnalyzer, GermanAnalyzer provided by Lucene).
     117Lucene index is stored in WEB-INF/lucene directory :
     118{{{
     119lucene
     120 +-- nonspatial_eng
     121 +-- nonspatial_fra
     122 +-- nonspatial_deu
     123}}}
     124
     125Metadata indexing is done in default language using index-fields.xsl and multilingual content using language-index-fields.xsl which will extract all fragments to be stored in index.
     126

     128
     129=== Search ===
     130Search is done using a MultiSearcher (ie. in all index) and the index corresponding to GUI language is "boost" to be on top.
     131A duplicate filter filter search result in order to not to have duplicate in results as one record will appear in more than on index.
