Doc bug: "solr.PatternCaptureGroupTokenFilter" s.b.
"solr.PatternCaptureGroupTokenFilterFactory"
Both the wiki and the Javadoc have the same issue.
Also, I just happened to notice that there is no unit test for the factory,
unlike other filter factories.

Subject: [Solr Wiki] Update of "AnalyzersTokenizersTokenFilters" by
ErikHatcher
Dear Wiki user,
You have subscribed to a wiki page or wiki category on "Solr Wiki" for
change notification.
The "AnalyzersTokenizersTokenFilters" page has been changed by ErikHatcher:
https://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters?action=diff&rev1=146&rev2=147
Comment:
added PatternCaptureGroupFilterFactory
. Example: `" Kittens! ", "Duck" ==> "Kittens!", "Duck"`.
Optionally, the "updateOffsets" attribute will update the start and end
position offsets.
+
+ <<Anchor(PatternCaptureGroupFilter)>>
+
+ === solr.PatternCaptureGroupFilterFactory ===
+ <!> [[Solr4.4]]
+
+ Emits tokens for each capture group in a regular expression
+
+ For example, the following definition will tokenize the input text of
"http://www.foo.com/index"; into "http://www.foo.com"; and "www.foo.com".
+
+ {{{
+ <fieldType name="url_base" class="solr.TextField"
positionIncrementGap="100">
+ <analyzer>
+ <tokenizer class="solr.KeywordTokenizerFactory">
+ <filter class="solr.PatternCaptureGroupTokenFilter"
pattern="(https?://([a-zA-Z\-_0-9.]+))" preserve_original="false">
+ </analyzer>
+ </fieldType>
+ }}}
+
+ If none of the patterns match, or if preserve_original is true, the
original token will also be emitted.
+
=== solr.PatternReplaceFilterFactory ===
Like the !PatternReplaceCharFilterFactory, but operates post-tokenization.
See "When to use a Char Filter vs. a Token Filter" above.
