SolrJ & Spatial Search

[SR <r....@gmail.com>]

Hi there,

Through SolrJ 3.2, I'm trying to set some Spatial Search queries (e.g., filter by distance, sort by distance, etc.). I don’t know whether there's a specific SolrJ syntax to do this. I tried using Strings, but it’s not working. Here’s are two examples that work fine on Solr, but don’t work when I use SolrJ:

Example 1:

	…

	String q = "{!func}geodist()&sfield=store&pt=” + lat + “,” + lon +”&sort=score asc";

	SolrQuery solrQuery = new SolrQuery();

	solrQuery.setQuery(q);

	… 

Using SolrJ, I get the following error.

	…

	org.apache.lucene.queryParser.ParseException: geodist - not enough parameters:[]  


Example 2:

	…

	String q = "*:*&sfield=store&sort=geodist() asc&pt=” + lat + “,” + lon;

	…

Using SolrJ, I get the following error

	…

	Caused by: org.apache.solr.common.SolrException: undefined field *



Do you know how to set these kinds of queries using SolrJ?
Thanks in advance for your help,

-S

    solrQuery.setQuery("*:*");
    solrQuery.addFilterQuery("{!func}geodist()");
    solrQuery.set("sfield", "store");
    solrQuery.set("pt", lat + "," + lon);
    solrQuery.set("sort", "geodist() asc");

I'm sorry, i'm trying to do the same as he is.
I've read your reply many times now, but i still don't know how to do this.

Would somebody help me with this? Thanks a lot

Saïd,
 The misunderstanding you have is that you are confusing the user query (the
q parameter) with the URL that Solr sees.  Well actually the part of the URL
that is called the query string -- that which is after the "?". SolrQuery
has various setters for well-known parameters, and others just use
solrQuery.setParam(name,value).
