Summary

This function constructs a geospatial path index specification. For usage details, see Geospatial Path Point Queries and Indexes in the Search Developer's Guide.

Parameters
pathexpr A valid XPath expression.
coordinate-system The coordinate system. Must be one of wgs84, wgs84/double, etrs89, etrs89/double, raw, raw/double.
range-value-positions A boolean specifying whether to maintain value positions in this index (used with co-occurrences).
point-format The point format in the data: "point" means latitude precedes longitude (this is the default); "long-lat-point" means longitude precedes latitude. To use the default value of "point", simply omit this parameter. Do not specify an empty string.
invalid-values An option to handle values that do not meet the range index type. Must be one of: reject, ignore.

Example


xquery version "1.0-ml";

import module namespace admin = "http://marklogic.com/xdmp/admin"

  "wgs84",
  fn:false(),
  "long-lat-point",
  "reject" )
=>
