Functions

func PurgeIndex

func PurgeIndex(c context.Context) error

PurgeIndex deletes all the packages from the search index.

func PutIndex

func PutIndex(c context.Context, pdoc *doc.Package, id string, score float64, importCount int) error

PutIndex creates or updates a package entry in the search index. id identifies the document in the index. If pdoc is non-nil, PutIndex will update the package's name, path and synopsis supplied by pdoc. pdoc must be non-nil for a package's first call to PutIndex. PutIndex updates the Score to score, if non-negative.
