@ -192,6 +192,11 @@ New Features
* SOLR-2438: Case insensitive search for wildcard queries. Actually, the ability to specify
a complete analysis chain for multiterm queries.
(Pete Sturge Erick Erickson, Mentoring from Seeley and Muir)
* SOLR-2918 Improvement to SOLR-2438, added MultiTermAwareComponent to the various classes
that should transform multiterm queries in various ways, and use this as the criteria for
adding them to the multiterm analyzer that is constructed if not specified in the

<!-- Illustrates the use of a new analyzer type "multiterm". See the Wiki page "Multiterm
Query Analysis" and SOLR-2438 for full details. The short form is that this analyzer is
applied to wildcard terms (prefix, wildcard range) if specified. This allows, among other
things, not having to lowercase wildcard terms on the client.
In the absence of this section, the new default behavior (3.6, 4.0) is to construct
one of these from the query analyzer that incorporates any defined charfilters, a
WhitespaceTokenizer, a LowerCaseFilter (if defined), and an ASCIIFoldingFilter
(if defined).
Arguably, this is an expert-level analyzer, most cases will be handled by an instance
of this being automatically constructed from the queryanalyzer.
