Class Hierarchy
This inheritance list is sorted roughly, but not completely, alphabetically:
[detail level 123456]
oCLucene.Net.Util.Cache.AbstractSegmentCacheRoot custom cache to allow a factory to retain references to the custom caches without having to be aware of the type.
oCLucene.Net.Index.ByteBlockPool.Allocator
oCSF.Snowball.Among
oCApplicationException
oCLucene.Net.Support.AppSettings
oCLucene.Net.Analysis.AR.ArabicNormalizer
oCLucene.Net.Analysis.AR.ArabicStemmer
oCArgumentException
oCLucene.Net.Util.ArrayUtilMethods for manipulating arrays.
oCAttribute
oCAttributeFactory
oCLucene.Net.Util.AttributeSource.AttributeFactoryAn AttributeFactory creates instances of Attributes.
oCLucene.Net.Util.AttributeSourceAn AttributeSource contains a list of different Attributes, and methods to add and get them. There can only be a single instance of an attribute in the same AttributeSource instance. This is ensured by passing in the actual type of the Attribute (Class<Attribute>) to the AddAttribute{T}(), which then checks if an instance of that type is already present. If yes, it returns the instance, otherwise it creates a new instance and returns it.
oCLucene.Net.Spatial.BBox.BBoxSimilarityAbstraction of the calculation used to determine how similar two Bounding Boxes are.
oCLucene.Net.Support.BitSetSupportThis class provides supporting methods of java.util.BitSet that are not present in System.Collections.BitArray.
oCLucene.Net.Util.BitUtilA variety of high efficiencly bit twiddling routines
oCLucene.Net.Search.BooleanClauseA clause in a BooleanQuery.
oCLucene.Net.Analysis.BR.BrazilianStemmer
oCLucene.Net.Index.BufferedDeletesHolds buffered deletes, by docID, term or query. We hold two instances of this class: one for the deletes prior to the last flush, the other for deletes after the last flush. This is so if we need to abort (discard all buffered docs) we can also discard the buffered deletes yet keep the deletes done during previously flushed segments.
oCBufferedIndexInput
oCLucene.Net.Support.BuildType
oCLucene.Net.Index.ByteBlockPool
oCLucene.Net.Index.ByteSliceWriterClass to write byte streams into slices of shared byte[]. This is used by DocumentsWriter to hold the posting list for many terms in RAM.
oCLucene.Net.Search.CacheEntryEXPERT: A unique Identifier/Description for each item in the FieldCache. Can be useful for logging/debugging. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.

oCLucene.Net.Index.CharBlockPool
oCLucene.Net.Index.CheckIndexBasic tool and API to check the health of an index and write a new segments file that removes reference to problematic segments
oCLucene.Net.Util.CloseableThreadLocalJava's builtin ThreadLocal has a serious flaw: it can take an arbitrarily long amount of time to dereference the things you had stored in it, even once the ThreadLocal instance itself is no longer referenced. This is because there is single, master map stored for each thread, which all ThreadLocals share, and that master map only periodically purges "stale" entries
oCLucene.Net.Support.CloseableThreadLocalProfilerFor Debuging purposes.
oCLucene.Net.Support.CollectionsHelperSupport class used to handle Hashtable addition, which does a check first to make sure the added item is unique in the hash.

oCLucene.Net.Search.DocIdSetA DocIdSet contains a set of doc ids. Implementing classes must only implement Iterator to provide access to the set.
oCDocIdSetIterator
oCLucene.Net.Search.DocIdSetIteratorThis abstract class defines methods to iterate over a set of non-decreasing doc ids. Note that this class assumes it iterates on doc Ids, and therefore NO_MORE_DOCS is set to Int32.MaxValue in order to be used as a sentinel object. Implementations of this class are expected to consider int.MaxValue as an invalid value.
oCLucene.Net.Documents.DocumentDocuments are the unit of indexing and search
oCLucene.Net.Index.DocumentsWriterThreadStateUsed by DocumentsWriter to maintain per-thread state. We keep a separate Posting hash and other state for each thread and then merge postings hashes from all threads when writing the segment.

oCLucene.Net.Search.FieldCache
oCLucene.Net.Search.FieldCache_Fields
oCLucene.Net.Util.FieldCacheSanityCheckerProvides methods for sanity checking that entries in the FieldCache are not wasteful or inconsistent. Lucene 2.9 Introduced numerous enhancements into how the FieldCache is used by the low levels of Lucene searching (for Sorting and ValueSourceQueries) to improve both the speed for Sorting, as well as reopening of IndexReaders. But these changes have shifted the usage of FieldCache from "top level" IndexReaders (frequently a MultiReader or DirectoryReader) down to the leaf level SegmentReaders. As a result, existing applications that directly access the FieldCache may find RAM usage increase significantly when upgrading to 2.9 or Later. This class provides an API for these applications (or their Unit tests) to check at run time if the FieldCache contains "insane" usages of the FieldCache. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.

oCLucene.Net.Index.TermVectorMapperThe TermVectorMapper can be used to map Term Vectors into your own structure instead of the parallel array structure used by Lucene.Net.Index.IndexReader.GetTermFreqVector(int,String). It is up to the implementation to make sure it is thread-safe
oCLucene.Net.Index.CheckIndex.Status.TermVectorStatusStatus from testing stored fields.
oCLucene.Net.Demo.Html.Test
oCSF.Snowball.TestApp
oCLucene.Net.Search.Highlight.TextFragmentLow-level class used to record information about a section of a document with a score.
oCTextReader
oCLucene.Net.Support.TextSupport
oCLucene.Net.Support.ThreadLockAbstract base class that provides a synchronization interface for derived lock types
oCLucene.Net.Search.Vectorhighlight.FieldPhraseList.WeightedPhraseInfo.Toffs
oCLucene.Net.Demo.Html.TokenDescribes the input token stream.
oCLucene.Net.QueryParsers.TokenDescribes the input token stream.
oCLucene.Net.Search.Highlight.TokenGroupOne, or several overlapping tokens, along with the score(s) and the scope of the original text
oCLucene.Net.Analysis.Shingle.TokenPositioner
oCLucene.Net.Analysis.Shingle.Codec.TokenSettingsCodecStrategy used to code and decode meta data of the tokens from the input stream regarding how to position the tokens in the matrix, set and retreive weight, etc.
oCLucene.Net.Search.Highlight.TokenSourcesHides implementation issues associated with obtaining a TokenStream for use with the higlighter - can obtain from TermFreqVectors with offsets and (optionally) positions or from Analyzer class reparsing the stored content.
oCLucene.Net.Search.TopDocsRepresents hits returned by Searcher.Search(Query,Filter,int) and Searcher.Search(Query,int)
oCLucene.Net.Util.ToStringUtilsHelper methods to ease implementing Object.ToString().
oCSpellChecker.Net.Search.Spell.TRStringDistanceEdit distance class
oCLucene.Net.Index.PositionBasedTermVectorMapper.TVPositionInfoContainer for a term at a position
oCLucene.Net.Search.Function.FieldScoreQuery.TypeType of score field, indicating how field values are interpreted/parsed. The type selected at search search time should match the data stored in the field. Different types have different RAM requirements:

  • BYTE consumes 1 * maxDocs bytes.
  • SHORT consumes 2 * maxDocs bytes.
  • INT consumes 4 * maxDocs bytes.
  • FLOAT consumes 8 * maxDocs bytes.
oCLucene.Net.Util.UnicodeUtil.UTF16Result
oCLucene.Net.Util.UnicodeUtil.UTF8Result
oCLucene.Net.Search.Function.ValueSourceExpert: source of values for basic function queries. At its default/simplest form, values - one per doc - are used as the score of that doc. Values are instantiated as DocValues for a particular reader. ValueSource implementations differ in RAM requirements: it would always be a factor of the number of documents, but for each document the number of bytes can be 1, 2, 4, or 8
oCLucene.Net.Search.WeightExpert: Calculate query weights and build query scorers. The purpose of Weight is to ensure searching does not modify a Query, so that a Query instance can be reused.
Searcher dependent state of the query should reside in the Weight.
IndexReader dependent state should reside in the Scorer. A Weight is used in the following way:

oCLucene.Net.Search.Vectorhighlight.FieldFragList.WeightedFragInfo
oCLucene.Net.Search.Vectorhighlight.FieldPhraseList.WeightedPhraseInfo
oCLucene.Net.Search.Highlight.WeightedSpanTermExtractorClass used to extract WeightedSpanTerms from a Query based on whether Terms from the Query are contained in a supplied Analysis.TokenStream.
oCLucene.Net.Search.Highlight.WeightedTermLightweight class to hold term and a Weight value used for scoring this term
oCLucene.Net.Store.Lock.WithUtility class for executing code with exclusive access.
\CLucene.Net.Analysis.WordlistLoaderLoader for text files that represent a list of stopwords.
