[Contrib] Extensions
--------------------

                 Key: LUCENENET-345
                 URL: https://issues.apache.org/jira/browse/LUCENENET-345
             Project: Lucene.Net
          Issue Type: New Feature
            Reporter: Michael Garski


I have created a few generic extensions to Lucene.Net that I use quiet a bit.  It's packaged
up as a VS2008 solution with two projects.  The test project is a Visual Studio test project
as opposed to NUnit, and that can be changed.  Here is a summary of the contents:

FieldEnumerators : provides foreach syntax support when enumerating over all of the terms
in the index.

TermVectorEnumerator : provides foreach syntax to allow for enumerating over all of the term
vectors in an index.

BooleanFilter : combine multiple query filters in various logical combinations.

TermsFilter : creates a filter from several terms as a logical OR.

SegmentCache : a generic cache that works with the segment-level searching in Lucene 2.9 to
cache any data at the segment level in the same manner as the field cache and  CachingWrapperFilter
which  I've used for caching aggregate data on the documents in a segment for use in diagnostics
and for caching TermVectors.  

SegmentsGenCommit : adds the ability to open an index from the version specified in the segments
file as opposed to inferring the version from the files in the index directory.

Refer to the documentation comments and unit tests for how to use the items.
