MarkLogic Server 11.0 Product DocumentationPath Range Index Configuration Help
An Path Range Index accelerates queries for comparisons within a specified type.
Each Path Range Index keeps track of the values appearing in all XML elements or JSON properties with a given name, type, and collation.
Path Range Indexes also
allow you to use the cts:values family of
lexicon APIs and to use the cts:path-range-query
constructor in searches.
Configure the following for each Path Range Index:
- The scalar type specifies the ordered domain for the index. Each of the types correspond with an XQuery type.
- path expression specifies the path.
- The collation specifies the collation to use in the comparison operations.
- range value positions specifies whether index data should be included that speeds up the performance of proximity queries involving range queries. Turn this index off if you are not interested in proximity queries and if you want to conserve disk space and decrease loading time.
- invalid values specifies whether server should allow insertion of documents that contain XML elements or JSON properties on which range index is configured and their contents cannot be coerced to the index data type. It can be configured to either ignore or reject. By default server rejects insertion of such documents. However, if a user configures invalid values to ignore, these documents can be inserted. This setting does not change the behavior of queries on invalid values after documents are inserted in the database. Performing an operation on an invalid value at query time can still result in an error.
Buttons and Tabs:
- Use the Configure tab to edit existing range path index configurations. Click the delete button corresponding to a range index to remove it.
- Use the Add tab to add new range path indexes to the database configuration.
