java - Spring Data MongoDB Overriding text index language in a compound index for inner fields -

here's document class:

@document(language = "russian")  @compoundindexes({         @compoundindex(def = "{'tempid' : 1, 'persons.title' : 'text', 'otherpersons.title' : 'text'}", background = true)})  public class companyhistory implements persistable<string> {  @id private string id;  private string tempid; private list<person> persons; private list<otherperson> otherpersons; ... } 

person , otherperson contains 2 strings, getteres, setters.

question: how override language on text index (defaults english) inner fields when building compound index? looks setting language works @textindexed annotation.

had similar problem (text index subentities) , tried find way set language_override , default_language via @compoundindex, nothing worked me.

finally ended following solution:

textindexdefinition textindex = new textindexdefinition.textindexdefinitionbuilder()         .withdefaultlanguage("none").withlanguageoverride("dummy")         .named("text_user_search")         .onfield("user.name")         .onfield("user.mail")         .build(); mongotemplate.indexops(user.class).ensureindex(textindex);
