type Optimizable 

type Optimizable interface {
	Optimize(kind string, octx OptimizableContext) (OptimizableContext, error)
}

Optimizable represents an optional interface that implementable by optimizable resources (e.g., TermFieldReaders, Searchers). These optimizable resources are provided the same OptimizableContext instance, so that they can coordinate via dynamic interface casting.

type OptimizableContext 

type OptimizableContext interface {
	// Once all the optimzable resources have been provided the same
	// OptimizableContext instance, the optimization preparations are
	// finished or completed via the Finish() method.
	//
	// Depending on the optimization being performed, the Finish()
	// method might return a non-nil Optimized instance.  For example,
	// the Optimized instance might represent an optimized
	// TermFieldReader instance.
	Finish() (Optimized, error)
}

type Optimized 

type Optimized interface{}

Represents a result of optimization -- see the Finish() method.

type Regexp 

type Regexp interface {
	FindStringIndex(s string) (loc []int)

	LiteralPrefix() (prefix string, complete bool)

	String() string
}

The Regexp interface defines the subset of the regexp.Regexp API methods that are used by bleve indexes, allowing callers to pass in alternate implementations.

type TermFieldDoc 

type TermFieldDoc struct {
	Term    string
	ID      IndexInternalID
	Freq    uint64
	Norm    float64
	Vectors []*TermFieldVector
}

func (*TermFieldDoc) Reset 

func (tfd *TermFieldDoc) Reset() *TermFieldDoc

Reset allows an already allocated TermFieldDoc to be reused

func (*TermFieldDoc) Size 

func (tfd *TermFieldDoc) Size() int

type TermFieldReader 

type TermFieldReader interface {
	// Next returns the next document containing the term in this field, or nil
	// when it reaches the end of the enumeration.  The preAlloced TermFieldDoc
	// is optional, and when non-nil, will be used instead of allocating memory.
	Next(preAlloced *TermFieldDoc) (*TermFieldDoc, error)

	// Advance resets the enumeration at specified document or its immediate
	// follower.
	Advance(ID IndexInternalID, preAlloced *TermFieldDoc) (*TermFieldDoc, error)

	// Count returns the number of documents contains the term in this field.
	Count() uint64
	Close() error

	Size() int
}

TermFieldReader is the interface exposing the enumeration of documents containing a given term in a given field. Documents are returned in byte lexicographic order over their identifiers.

type TermFieldVector 

type TermFieldVector struct {
	Field          string
	ArrayPositions []uint64
	Pos            uint64
	Start          uint64
	End            uint64
}

func (*TermFieldVector) Size 

func (tfv *TermFieldVector) Size() int
