Index Functions
This module provides functions for displaying information stored in the database index structures.
For functions that use the indexes to return nodes, browse through the Database Functions and ft:search.
All functions and errors are in the http://basex.org/modules/index namespace, to which the index prefix is statically bound.
| Signature | index:facets(
$database as xs:string,
$type as xs:string? := ()
) as xs:string |
|---|
| Summary | Returns information about all facets and facet values of the database $database in document structure format. If $type is specified as flat, the function returns this information in a flat summarized version. The returned data is derived from the Path Index. |

| Examples | index:facets("DB")
Returns information about facets and facet values on the database DB in document structure.
index:facets("DB", "flat")
Returns information about facets and facet values on the database DB in a summarized flat structure. |

| Signature | index:texts(
$database as xs:string,
$prefix as xs:string := (),
$ascending as xs:boolean? := false()
) as element(value)* |
|---|
| Summary | Returns all strings stored in the Text Index of the database $database, along with their number of occurrences. If $prefix is specified, the returned entries will be refined to the ones starting with that prefix. If $prefix and $ascending are specified, all nodes will be returned after or before the specified entry. |

| Signature | index:attributes(
$database as xs:string,
$prefix as xs:string := (),
$ascending as xs:boolean? := false()
) as element(value)* |
|---|
| Summary | Returns all strings stored in the Attribute Index of the database $database, along with their number of occurrences. If $prefix is specified, the returned entries will be refined to the ones starting with that prefix. If $prefix and $ascending are specified, all nodes will be returned after or before the specified start entry. |

| Signature | index:tokens(
$database as xs:string
) as element(value)* |
