BleveToCondFlexIndexes translates a bleve index into CondFlexIndexes.

Recursively initializes a FlexIndex from a given bleve document mapping.

CFTArray() looks for range comparisons that tells us that a field is an array.

CFTNumber() looks for range comparisons that tells us that a field is a number.

CFTString() looks for range comparisons that tells us that a field is a string.

Checks whether an expr, such as `emp`.`locations`.`work`.`address`.`city`, is a nested fields reference against the identifiers (e.g., "emp"), and also has a given prefix (e.g., ["locations", "work"]), and if so returns the remaining field path suffix (e.g., ["address", "city"]).

FlexBuildToBleveQuery translates a flex build tree into a bleve query tree in map[string]interface{} representation.

LearnConjunctFieldTypes examines the conjunct exprs (e.g., children of an "AND" expression) to discover field-type information.

Returns a CondFunc that represents checking a field for value equality.

Returns a CondFunc that represents checking a field is not equal to any of the given vals.

This map contains types that Bleve supports for N1QL queries.

This map translates Bleve's supported types to types as identified by N1QL.

Associates a condition check to a FlexIndex, used for type mappings.

ConjunctFieldTypes represents state as a conjunct expression is examined and processed for field-type information.

FlexBuild represents hierarchical state that's gathered during Sargable() recursion, which can be used to formulate an index scan.

FlexIndex represents the subset of a flexible index definition that's needed for sargable processing.

SupportedExprCmpFieldConstant implements the SupportedExpr interface and represents a comparison of a field to a constant value with a given type.

A supported expression that never matches, useful for debugging.

A supported expression that always returns not-sargable, useful to mark unknown exprs as not-sargable rather than as filterable.

Allows apps to declare supported expressions to FlexSargable().

A slice of conditional flex indexes.

Returns true when the expressions match the condition check, also returns an array of the requested "types" (obtained from query).

Used to track field-type learnings, FieldTypes is a copy-on-write, left-side-pushed stack of immutable dictionaries.
