request SOLR - spatial field with Intersect and Contains functions
Hi,
I am trying spatial search in SOLR 5.0 and I don't know how to implement
a solution for the problem I will try to explain.
On a SOLR server I have indexed a collection of objects that contains
spacial field :
<field name="geo" type="location_rpt" indexed="true" stored="true"
multiValued="true" />
<fieldType name="location_rpt"
class="solr.SpatialRecursivePrefixTreeFieldType"
geo="true"
distErrPct="0.025"
maxDistErr="0.000009"
distanceUnits="degrees" />
The spatial data indexed in the field named "geo" can be ENVELOPE or
LINESTRING :
<field name="geo">LINESTRING(-4.6837 48.5792, -4.6835 48.5788, -4.684
48.5788, -4.6832 48.579, -4.6837 48.5792, -4.6188 48.6265, -4.6122
48.63, -4.615 48.6258, -4.6125 48.6215, -4.6112 48.6218)</field>
or
<field name="geo">ENVELOPE(-5.0, -4.0, 49.0, 48.0)</field>
Actually in my application, when I do a SOLR request to get objects that
are in a spatial area, I do something like this :
q=:&fq=(geo:"Intersects(ENVELOPE(-116.894531, 107.402344, 57.433227,
-42.146973))")
But I want to change how it work. Now, when the geo field contain an
ENVELOPE I want to do an CONTAINS request and when it contain a
LINESTRING I want to do an INTERSECTS request.
example :
If geo = ENVELOPE then q=*:*&fq=(geo:"Contains(ENVELOPE(-116.894531,
107.402344, 57.433227, -42.146973))")
If geo = LINESTRING then q=*:*&fq=(geo:"Intersects(ENVELOPE(-116.894531,
107.402344, 57.433227, -42.146973))")
How can my application know if the field contain ENVELOPE or LINESTRING ?
Any idea can this be done ?
Best reguards,
Leo.

Hi Leo,
You should use two spatial fields for this -- one is for an indexed
Box/Envelope, and another for an indexed LineString. The indexed box
should use either BBoxField or RptWithGeometrySpatialField, and the
LineString field should use RptWithGeometrySpatialField. If you have an
older installation 5.x version, RptWithGeometrySpatialField may not be
available in which case settle
for solr.SpatialRecursivePrefixTreeFieldType. When you do a search, it'd
be a search for one field OR the other with the requirements you have for
each.

request SOLR - spatial field with Intersect and Contains functions
Posted by Leo BRUVRY-LAGADEC <Le...@partenaire-exterieur.ifremer.fr>.
Hi list,
I am trying spatial search in SOLR 5.0 and I don't know how to implement
a solution for the problem I will try to explain.
On a SOLR server I have indexed a collection of objects that contains
spacial field :
<field name="geo" type="location_rpt" indexed="true" stored="true"
multiValued="true" />
<fieldType name="location_rpt"
class="solr.SpatialRecursivePrefixTreeFieldType"
geo="true"
distErrPct="0.025"
maxDistErr="0.000009"
distanceUnits="degrees" />
The spatial data indexed in the field named "geo" can be ENVELOPE or
LINESTRING :
<field name="geo">LINESTRING(-4.6837 48.5792, -4.6835 48.5788, -4.684
48.5788, -4.6832 48.579, -4.6837 48.5792, -4.6188 48.6265, -4.6122
48.63, -4.615 48.6258, -4.6125 48.6215, -4.6112 48.6218)</field>
or
<field name="geo">ENVELOPE(-5.0, -4.0, 49.0, 48.0)</field>
Actually in my application, when I do a SOLR request to get objects that
are in a spatial area, I do something like this :
q=:&fq=(geo:"Intersects(ENVELOPE(-116.894531, 107.402344, 57.433227,
-42.146973))")
But I want to change how it work. Now, when the geo field contain an
ENVELOPE I want to do an CONTAINS request and when it contain a
LINESTRING I want to do an INTERSECTS request.
example :
If geo = ENVELOPE then q=*:*&fq=(geo:"Contains(ENVELOPE(-116.894531,
107.402344, 57.433227, -42.146973))")
If geo = LINESTRING then q=*:*&fq=(geo:"Intersects(ENVELOPE(-116.894531,
107.402344, 57.433227, -42.146973))")
How can my application know if the field contain ENVELOPE or LINESTRING ?
Any idea can this be done ?
