This module is introduced with BaseX Template:Mark. It contains XQuery functions for handling informations coming directly from the indexes within XQuery. All functions are introduced with the index:
prefix, which is linked to the http://www.basex.org/modules/index
namespace.
index:facets
Signatures | index:facets($db as item()) as xs:string index:facets($db as item(), $type as xs:string) as xs:string
|
Summary | Returns information about possible facets and facet values on a database in document structure format. $db may either be an xs:string , denoting the database name, or a node stored in the database.If $type is specified as flat , the function returns this information in a flat summarized version.
|
Errors | BASX0002 is raised if $db is a node that is not stored in a database.BASX0003 is raised if the addressed database $db cannot be opened.BASX0021 is raised if the index is not available or doesn't have the needed information. |
Examples |
|
Errors | BASX0001 is raised if the path index is not available. BASX0002 is raised if $db is a node that is not stored in a database.BASX0003 is raised if the addressed database $db cannot be opened. |
index:texts
Signatures | index:texts($db as item()) as element(value)* index:texts($db as item(), $prefix as xs:string) as element(value)*
|
Summary | Returns all strings stored in the text index, along with their number of occurrence. $db may either be an xs:string , denoting the database name, or a node stored in the database.If $prefix is specified, the returned nodes will be refined to the strings starting with that prefix.
|
Errors | BASX0001 is raised if the text index is not available. BASX0002 is raised if $db is a node that is not stored in a database.BASX0003 is raised if the addressed database $db cannot be opened. |
index:attributes
Signatures | index:attributes($db as item()) as element(value)* index:attributes($db as item(), $prefix as xs:string) as element(value)*
|
Summary | Returns all strings stored in the attribute index, along with their number of occurrence. $db may either be an xs:string , denoting the database name, or a node stored in the database.If $prefix is specified, the returned nodes will be refined to the strings starting with that prefix.
