DemoHTMLParser.Parser: The actual parser to read HTML documents
DirContentSource: A `ContentSource` using the Dir collection for its input.
DirContentSource.Iterator: Iterator over the files in the directory
DocData: Output of parsing (e.g.
DocMaker: Creates `Document` objects.
DocMaker.DocState: Document state, supports reuse of field instances across documents (see `reuseFields` parameter).
EnwikiContentSource: A `ContentSource` which reads the English Wikipedia dump.
EnwikiQueryMaker: A QueryMaker that uses common and uncommon actual Wikipedia queries for searching the English Wikipedia collection.

GeonamesLineParser: A line parser for Geonames.org data.
LineDocSource: A `ContentSource` reading one line at a time as a `Document` from a single file.
LineDocSource.HeaderLineParser: `LineDocSource.LineParser` which sets field names and order by the header - any header - of the lines file.
LineDocSource.LineParser: Reader of a single input line into `DocData`.
LineDocSource.SimpleLineParser: `LineDocSource.LineParser` which ignores the header passed to its constructor and assumes simply that field names and their order are the same as in `WriteLineDocTask.DEFAULT_FIELDS`
LongToEnglishContentSource: Creates documents whose content is a `long` number starting from ``Long.MIN_VALUE` + 10`.
LongToEnglishQueryMaker: Creates queries whose content is a spelled-out `long` number starting from ``Long.MIN_VALUE` + 10`.
RandomFacetSource: Simple implementation of a random facet source
ReutersContentSource: A `ContentSource` reading from the Reuters collection.
ReutersQueryMaker: A QueryMaker that makes queries devised manually (by Grant Ingersoll) for searching in the Reuters collection.
SimpleQueryMaker: A QueryMaker that makes queries for a collection created using `SingleDocSource`.
SimpleSloppyPhraseQueryMaker: Create sloppy phrase queries for performance test, in an index created using simple doc maker.
SingleDocSource: Creates the same document each time `SingleDocSource.getNextDocData(DocData)` is called.
SortableSingleDocSource: Adds fields appropriate for sorting: country, random_string and sort_field (int).
SpatialDocMaker: Indexes spatial data according to a configured `SpatialStrategy` with optional shape transformation via a configured `SpatialDocMaker.ShapeConverter`.
SpatialFileQueryMaker: Reads spatial data from the body field docs from an internally created `LineDocSource`.
TrecContentSource: Implements a `ContentSource` over the TREC collection.
TrecDocParser: Parser for trec doc content, invoked on doc text excluding <DOC> and <DOCNO> which are handled in TrecContentSource.
TrecFBISParser: Parser for the FBIS docs in trec disks 4+5 collection format
TrecFR94Parser: Parser for the FR94 docs in trec disks 4+5 collection format

TrecGov2Parser: Parser for the GOV2 collection format
TrecLATimesParser: Parser for the FT docs in trec disks 4+5 collection format
TrecParserByPath: Parser for trec docs which selects the parser to apply according to the source files path, defaulting to `TrecGov2Parser`.
