Overview ¶

Package indexer indexes objects that implement the Indexable interface. The index is all in memory right now, but it can be frozen and saved to disk for persistence.

Functions ¶

func ClearIndex ¶ added in v0.3.3

func ClearIndex()

ClearIndex of all collections and documents

func CreateNewCollection ¶

func CreateNewCollection(idxName string)

CreateNewCollection creates an index for data bags when they are created, rather than when the first data bag item is uploaded

func DeleteCollection ¶

func DeleteCollection(idxName string) error

DeleteCollection deletes a collection from the index. Useful only for data bags.

func DeleteItemFromCollection ¶

func DeleteItemFromCollection(idxName string, doc string) error

DeleteItemFromCollection deletes an item from a collection

func Endpoints ¶

func Endpoints() []string

Endpoints returns a list of currently indexed endpoints.

func IndexObj ¶

func IndexObj(object Indexable)

IndexObj processes and adds an object to the index.

func LoadIndex ¶ added in v0.3.0

func LoadIndex(idxFile string) error

LoadIndex loads index files from disk.

func ReIndex ¶ added in v0.3.3

func ReIndex(objects []Indexable) error

ReIndex rebuilds the search index from scratch

func SaveIndex ¶ added in v0.3.0

func SaveIndex(idxFile string) error

SaveIndex saves the index files to disk.

func SearchIndex ¶

func SearchIndex(idxName string, term string, notop bool) (map[string]*IdxDoc, error)

SearchIndex searches for a string in the given index. Returns a slice of names of matching objects, or an error on failure.

func SearchRange ¶

func SearchRange(idxName string, field string, start string, end string, inclusive bool) (map[string]*IdxDoc, error)

SearchRange performs a range search on the given index.

func SearchText ¶

func SearchText(idxName string, term string, notop bool) (map[string]*IdxDoc, error)

SearchText performs a full-ish text search of the index.

Types ¶

type IdxCollection ¶

type IdxCollection struct {
	// contains filtered or unexported fields
}

IdxCollection holds a map of documents.

func (*IdxCollection) GobDecode ¶ added in v0.3.0

func (ic *IdxCollection) GobDecode(buf []byte) error

func (*IdxCollection) GobEncode ¶ added in v0.3.0

func (ic *IdxCollection) GobEncode() ([]byte, error)

type IdxDoc ¶

type IdxDoc struct {
	// contains filtered or unexported fields
}

IdxDoc is the indexed documents that are actually searched.

func (*IdxDoc) Examine ¶

func (idoc *IdxDoc) Examine(term string) (bool, error)

Examine searches a document, determining if it needs to do a search for an exact term or a regexp search.

func (*IdxDoc) GobDecode ¶ added in v0.3.0

func (idoc *IdxDoc) GobDecode(buf []byte) error

func (*IdxDoc) GobEncode ¶ added in v0.3.0

func (idoc *IdxDoc) GobEncode() ([]byte, error)

func (*IdxDoc) RangeSearch ¶

func (idoc *IdxDoc) RangeSearch(field string, start string, end string, inclusive bool) (bool, error)

RangeSearch searches for a range of values.

func (*IdxDoc) TextSearch ¶

func (idoc *IdxDoc) TextSearch(term string) (bool, error)

TextSearch performs a text search of an index document.

type Index ¶

type Index struct {
	// contains filtered or unexported fields
}

Index holds a map of document collections.

func (*Index) GobDecode ¶ added in v0.3.0

func (i *Index) GobDecode(buf []byte) error

func (*Index) GobEncode ¶ added in v0.3.0

func (i *Index) GobEncode() ([]byte, error)

type Indexable ¶

type Indexable interface {
	DocID() string
	Index() string
	Flatten() []string
}

Indexable is an interface that provides all the information necessary to index an object. All objects that will be indexed need to implement this.
