MoreLikeThisComponent	TODO!
PhrasesIdentificationComponent	A component that can be used in isolation, or in conjunction with QueryComponent to identify & score "phrases" found in the input string, based on shingles in indexed fields.
PhrasesIdentificationComponent.Phrase	Model the data known about a single (candidate) Phrase -- which may or may not be indexed
PhrasesIdentificationComponent.PhrasesContextData	Simple container for all request options and data this component needs to store in the Request Context
PivotFacet	Models a single instance of a "pivot" specified by a FacetParams.FACET_PIVOT param, which may contain multiple nested fields.
PivotFacetField	Models a single field somewhere in a hierarchy of fields as part of a pivot facet.
PivotFacetFieldValueCollection	Emcapsulates a collection of PivotFacetValues associated with a PivotFacetField withs pecial tracking of a PivotFacetValue corrisponding to the null value when FacetParams.FACET_MISSING is used.
PivotFacetFieldValueCollection.PivotFacetCountComparator	Sorts PivotFacetValue instances by their count
PivotFacetFieldValueCollection.PivotFacetValueComparator	Sorts PivotFacetValue instances by their value
PivotFacetHelper
PivotFacetProcessor	Processes all Pivot facet logic for a single node -- both non-distrib, and per-shard
PivotFacetValue	Models a single (value, count) pair that will exist in the collection of values for a PivotFacetField parent.
QueryComponent	TODO!
QueryComponent.ScoreAndDoc	Fake scorer for a single document TODO: when SOLR-5595 is fixed, this wont be needed, as we dont need to recompute sort values here from the comparator
QueryElevationComponent	A component to elevate some documents to the top of the result set.
QueryElevationComponent.ElevatingQuery	Query triggering elevation.
QueryElevationComponent.Elevation	Elevation of some documents in search results, with potential exclusion of others.
RangeFacetProcessor	Processor for Range Facets
RangeFacetRequest	Encapsulates a single facet.range request along with all its parameters.
RangeFacetRequest.FacetRange	Represents a single facet range (or gap) for which the count is to be calculated
RealTimeGetComponent
ResponseBuilder	This class is experimental and will be changing in the future.
