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 ?
Best reguards,
Leo.
