Namespace Lucene.Net.Search.VectorHighlight

A abstract implementation of IFragListBuilder.

Base IFragmentsBuilder implementation that supports colored pre/post tags and multivalued fields.

Uses IBoundaryScanner to determine fragments.

A IBoundaryScanner implementation that uses BreakIterator to find boundaries in the text.

Another highlighter implementation.

FieldFragList has a list of "frag info" that is used by IFragmentsBuilder class to create fragments (snippets).

List of term offsets + weight for a frag info

Represents the list of term offsets for some text

FieldPhraseList has a list of WeightedPhraseInfo that is used by FragListBuilder to create a FieldFragList object.

Represents the list of term offsets and boost for some text

Term offsets (start + end)

FieldQuery breaks down query object into terms/phrases and keeps them in a FieldQuery.QueryPhraseMap structure.

Internal structure of a query for highlighting: represents a nested query structure

FieldTermStack is a stack that keeps query terms in the specified field of the document to be highlighted.

Single term with its position/offsets in the document and IDF weight. It is but considers only position.

An implementation of FragmentsBuilder that outputs score-order fragments.

for FieldFragList.WeightedFragInfo by boost, breaking ties by offset.

Simple boundary scanner implementation that divides fragments based on a set of separator characters.

A simple implementation of FieldFragList.

A simple implementation of IFragListBuilder.

A simple implementation of FragmentsBuilder.

An implementation class of IFragListBuilder that generates one FieldFragList.WeightedFragInfo object. Typical use case of this class is that you can get an entire field contents by using both of this class and SimpleFragmentsBuilder.

FastVectorHighlighter h = new FastVectorHighlighter( true, true,
    new SingleFragListBuilder(), new SimpleFragmentsBuilder() );

A weighted implementation of FieldFragList.

A weighted implementation of IFragListBuilder.

Finds fragment boundaries: pluggable into BaseFragmentsBuilder

IFragListBuilder is an interface for FieldFragList builder classes. A IFragListBuilder class can be plugged in to Highlighter.

IFragmentsBuilder is an interface for fragments (snippets) builder classes. A IFragmentsBuilder class can be plugged in to FastVectorHighlighter.
