Classes in org.apache.lucene.facet.taxonomy used by org.apache.lucene.facet

TaxonomyReader
TaxonomyReader is the read-only interface with which the faceted-search library uses the taxonomy during search time.

TaxonomyWriter
TaxonomyWriter is the interface which the faceted-search library uses to dynamically build the taxonomy at indexing time.

AssociationFacetField
Add an instance of this to your Document to add a facet label associated with an arbitrary byte[].

CategoryPath
Holds a sequence of string components, specifying the hierarchical name of a category.

FacetLabel
Holds a sequence of string components, specifying the hierarchical name of a category.

FloatTaxonomyFacets
Base class for all taxonomy-based facets that aggregate to a per-ords float[].

IntTaxonomyFacets
Base class for all taxonomy-based facets that aggregate to a per-ords int[].

LRUHashMap
LRUHashMap is an extension of Java's HashMap, which has a bounded size(); When it reaches that size, each time a new element is added, the least recently used (LRU) entry is removed.

OrdinalsReader
Provides per-document ordinals.

OrdinalsReader.OrdinalsSegmentReader
Returns ordinals for documents in one segment.

ParallelTaxonomyArrays
Returns 3 arrays for traversing the taxonomy: parents: parents[i] denotes the parent of category ordinal i. children: children[i] denotes a child of category ordinal i. siblings: siblings[i] denotes the sibling of category ordinal i. To traverse the taxonomy tree, you typically start with children[0] (ordinal 0 is reserved for ROOT), and then depends if you want to do DFS or BFS, you call children[children[0]] or siblings[children[0]] and so forth, respectively.

SearcherTaxonomyManager.SearcherAndTaxonomy
Holds a matched pair of IndexSearcher and TaxonomyReader

TaxonomyFacets
Base class for all taxonomy-based facets impls.

TaxonomyReader.ChildrenIterator
An iterator over a category's children.
