Remarks

Params are in the form argname:argvalue or argname:"argvalue" or argname:'argvalue'; use backslashes to escape '"' or "'" inside a quoted value when it's used as the enclosing quotation mark,

Specify params in a comma separated list of the following, in order:

    • Required: name:analyzer-factory-name
    • Optional: positionIncrementGap:int value (default: 0)
    • Optional: offsetGap:int value (default: 1)
  2. zero or more CharFilterFactory's, followed by
  3. exactly one TokenizerFactory, followed by
  4. zero or more TokenFilterFactory's

Each component analysis factory map specify luceneMatchVersion (defaults to LUCENE_CURRENT) and any of the args understood by the specified *Factory class, in the above-describe param format.

Example:

    -AnalyzerFactory(name:'strip html, fold to ascii, whitespace tokenize, max 10k tokens',
                     positionIncrementGap:100,
                     HTMLStripCharFilter,
                     MappingCharFilter(mapping:'mapping-FoldToASCII.txt'),
                     WhitespaceTokenizer(luceneMatchVersion:LUCENE_43),
                     TokenLimitFilter(maxTokenCount:10000, consumeAllTokens:false))
    [...]
    -NewAnalyzer('strip html, fold to ascii, whitespace tokenize, max 10k tokens')

AnalyzerFactory will direct analysis component factories to look for resources under the directory specified in the "work.dir" property.

Methods

Name Description
DoLogic()
GetLineNumber(StreamTokenizer)

Returns the current line in the algorithm file
LookupAnalysisClass(String, Type)

This method looks up a class with its fully qualified name (FQN), or a short-name class-simplename, or with a package suffix, assuming "Lucene.Net.Analysis." as the namespace prefix (e.g. "standard.ClassicTokenizerFactory" -> "Lucene.Net.Analysis.Standard.ClassicTokenizerFactory").
SetParams(String)

Sets the params. Analysis component factory names may optionally include the "Factory" suffix.
