Functions

func BucketFromPropName

func BucketFromPropName(propName string) []byte

BucketFromPropName creates the byte-representation used as the bucket name for a partiular prop in the inverted index

func BucketFromPropNameLSM

func BucketFromPropNameLSM(propName string) string

BucketFromPropName creates the byte-representation used as the bucket name for a partiular prop in the inverted index

func BucketFromPropNameLengthLSM

func BucketFromPropNameLengthLSM(propName string) string

func BucketFromPropNameNullLSM

func BucketFromPropNameNullLSM(propName string) string

func CountDuplicates

func CountDuplicates(parts []string) ([]string, []int)

func HashBucketFromPropNameLSM

func HashBucketFromPropNameLSM(propName string) string

HashBucketFromPropName creates the byte-representation used as the bucket name for the status information of a partiular prop in the inverted index

func HashBucketFromPropNameLengthLSM

func HashBucketFromPropNameLengthLSM(propName string) string

func HashBucketFromPropNameNullLSM

func HashBucketFromPropNameNullLSM(propName string) string

func MetaCountProp

func MetaCountProp(propName string) string

MetaCountProp helps create an internally used propName for meta props that don't explicitly exist in the user schema, but are required for proper indexing, such as the count of arrays.

func TempBucketFromBucketName

func TempBucketFromBucketName(bucketName string) string

func TokenizeString

func TokenizeString(in string) []string

TokenizeString only splits on white spaces, it does not alter casing

func TokenizeStringAndCountDuplicates

func TokenizeStringAndCountDuplicates(in string) ([]string, []int)

func TokenizeText

func TokenizeText(in string) []string

Tokenize Text splits on any non-alphanumerical and lowercases the words

func TokenizeTextAndCountDuplicates

func TokenizeTextAndCountDuplicates(in string) ([]string, []int)

func TokenizeTextKeepWildcards

func TokenizeTextKeepWildcards(in string) []string

Tokenize Text splits on any non-alphanumerical except wildcard-symbols and lowercases the words

func TrimString

func TrimString(in string) string

TrimString trims on white spaces
