[GeoNetwork-devel] Temporal searches

Jose_Garcia1 · October 10, 2014, 9:34am

Hi

Anyone know why the temporal search in the LuceneQueryBuilder works like this:

temporal extent start is within search extent
or temporal extent end is within search extent
or temporal extent contains search extent

The third condition, if you search from an “invalid” range: (from: 2014-10-07, to: 2013-01-01) causes to return results as produces a lucene query term like: tempExtentEnd:[2013-01-01 TO ], tempExtentBegin:[ TO 2014-10-10]

Sorry, but I don’t get the reason of this condition, except maybe to be more permissive in the searches? But anyway, produces bizarre results.

See the code in https://github.com/geonetwork/core-geonetwork/blob/develop/core/src/main/java/org/fao/geonet/kernel/search/LuceneQueryBuilder.java#L598

Thanks and regards,
Jose García

Hi Jose,

I think the temporal search works in a more permissive ‘overlapping’ mode i.e you will get anything inside the temporal range

you specify or anything that overlaps.

I you needed more exact control over the search range

you can use CSW search e.g this worked to give me all records within or equal to a range:

= AND <= (inclusive range)

<?xml version="1.0" encoding="UTF-8"?>

<ogc:Filter xmlns:gml=“http://www.opengis.net/gml” xmlns:ogc=“http://www.opengis.net/ogc”>

ogc:And

ogc:PropertyIsGreaterThanOrEqualTo

ogc:PropertyNameTempExtent_begin</ogc:PropertyName>

ogc:Literal1990-01-01T22:21:56.000Z</ogc:Literal>

</ogc:PropertyIsGreaterThanOrEqualTo>

ogc:PropertyIsLessThanOrEqualTo

ogc:PropertyNameTempExtent_end</ogc:PropertyName>

ogc:Literal2009-12-31Z</ogc:Literal>

</ogc:PropertyIsLessThanOrEqualTo>

</ogc:And>

</ogc:Filter>

Hi Andrew

I can’t use CSW for this, but thanks for confirming my suspects about the reason for this.
