Spatial search - indexing WKT data

[Leila Deljkovic <le...@koordinates.com>]

Hi,

I have some data in WKT string format (either POLYGON or MULTIPOLYGON) and I’d like to index it in Solr 7.0. As there are multiple polygons in every WKT string, I’d ideally like to index them multiValued BBoxField (couldn’t find anywhere to confirm, but it looks like multiValued is a valid attribute for BBoxField). Anyone indexed WKT data in Solr before? Is it necessary to convert it to CSV (I would do that first but I’m having trouble exporting it as CSV…)?

Thanks

It's been a while since I did it, but I'm pretty sure that when I indexed
polygons a couple years ago, I just sent WKT text for the field value... I
think i do recall some niggle where there was some slight mismatch in wkt
accepted by the javascript library I wanted to use and solr. (One was
slightly more permissive about something). As for fields I was using RPT
fields, which is more appropriate for arbitrary polygons I believe... also
note you may need to add JTS to solr as described here:
https://lucene.apache.org/solr/guide/7_2/spatial-search.html#jts-and-polygons-flat

I do think the Solr docs really should have examples of indexing these more
interesting field types. Presently the docs are pretty query focused...
