Salience offers an expanded list of languages with "second tier" support, consisting only of queries and document level model sentiment. These languages are used like any other language pack, except that when a session is initialized with a second tier language only the following functions are supported (the others will return an "LXA_UNAVAILABLE_IN_CURRENT_SESSION" error):

lxaPrepareText
lxaPrepareTextFromFile
lxaSetSalienceOption
lxaGetSentiment
lxaGetQueryDefinedTopics

The following languages are currently under second tier support:

Russian (RU)
Arabic (AR)
Norwegian (NO)
Swedish (SV)
Danish (DA)
