Take the 2-minute tour ×  We're running into a serious bug with
the Lucene.NET 2.3 codebase. We're upgrading to Lucene 2.9 in
hopes the bug is fixed.  Upgrading to the latest version, we see
that the MultiFieldQueryParser contructor is [Obsolete]:
[Obsolete("Use the ctor with Version param instead.")] public
MultiFieldQueryParser(string[] fields, Analyzer analyzer)
Instead, we're to use the constructor that takes a Version
parameter:  public MultiFieldQueryParser(Version version,
string[] fields, Analyzer analyzer)  Problem is, I can't find
any documentation regarding what the version parameter is, what
it's supposed to be, what I'm supposed to pass in here.  Can
anyone shine some light on this?  share|improve this question  1
Answer 1  up vote 5 down vote accepted  The version parameter
was added to provide backwards compatibility in a way that can
be extended to accommodate future changes.  If you don't care
about backwards compatibility, just use Version.LUCENE_CURRENT.
