如何将Spatial Solr添加到Solrnet查询(How to add Spatial Solr to a Solrnet query)

我在使用码头的Windows机器上运行Solr。 我已经下载了我最终设法启动并运行的Spatial Solr插件 。 我也使用Solrnet从我的asp.net mvc项目查询Solr。

现在,将数据添加到我的索引似乎工作正常,并且SpatialTierUpdateProcessorFactory也工作。

问题是:

如何使用Solrnet库将空间查询添加到正常查询中。 我曾尝试使用“ExtraParams”参数添加它,但是这并没有很好地发挥作用。

这里是我试图将空间查询与数据范围查询结合起来的一个例子。 日期范围查询在没有附加空间查询的情况下正常工作:

new SolrQuery("{!spatial lat=51.5224 long=-2.6257 radius=10000 unit=km calc=arc threadCount=2}") && new SolrQuery(MyCustomQuery.Query) && new SolrQuery(DateRangeQuery);

这会导致针对Solr的以下查询:

(({!spatial lat=51.5224 long=-2.6257 radius=100 unit=km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:13:37Z TO 2011-05-07T13:13:37Z])

我收到的错误信息是:

远程服务器返回错误:(400)错误的请求。

SEVERE: org.apache.solr.common.SolrException: org.apache.lucene.queryParser.Pars
eException: Cannot parse '(({!spatial lat=51.5224 lng=-2.6257 radius=10000 unit=
km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:09:49Z TO 2011-05-0
7T13:09:49Z])': Encountered " <RANGEEX_GOOP> "lng=-2.6257 "" at line 1, column 2
4.
Was expecting:
    "}" ...

现在,如果我使用Solr Web Admin页面并对它执行以下查询,则一切正常。

{!spatial lat=50.8371 long=4.35536 radius=100 calc=arc unit=km threadcount=2}text:London

使用SolrNet调用空间函数的最佳/正确方法是什么? 以某种方式将查询手动添加到查询字符串中的最佳方法是如何?


I am running Solr on my windows machine using jetty. I have downloaded the Spatial Solr Plugin which I finally managed to get up and running. I am also using Solrnet to query against Solr from my asp.net mvc project.

Now, adding data into my index seems to work fine and the SpatialTierUpdateProcessorFactory does work as well.

The problem is:

How do I add the spatial query to my normal query using the Solrnet library. I have tried adding it using the "ExtraParams" parameter but that didn't work very well.

Here is an example of me trying to combine the spatial query with a data range query. The date range query works fine without the spatial query attached to it:

new SolrQuery("{!spatial lat=51.5224 long=-2.6257 radius=10000 unit=km calc=arc threadCount=2}") && new SolrQuery(MyCustomQuery.Query) && new SolrQuery(DateRangeQuery);

which results in the following query against Solr:

(({!spatial lat=51.5224 long=-2.6257 radius=100 unit=km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:13:37Z TO 2011-05-07T13:13:37Z])

And the error message I get back is:

The remote server returned an error: (400) Bad Request.

SEVERE: org.apache.solr.common.SolrException: org.apache.lucene.queryParser.Pars
eException: Cannot parse '(({!spatial lat=51.5224 lng=-2.6257 radius=10000 unit=
km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:09:49Z TO 2011-05-0
7T13:09:49Z])': Encountered " <RANGEEX_GOOP> "lng=-2.6257 "" at line 1, column 2
4.
Was expecting:
    "}" ...

Now, the thing is if I use the Solr Web Admin page and execute the following query against it, everything works fine.

{!spatial lat=50.8371 long=4.35536 radius=100 calc=arc unit=km threadcount=2}text:London

What is the best/correct way to call the spatial function using SolrNet. Is the best way to somehow add that bit of the query manually to the query string and is so how?

最满意答案

你有没有尝试过:

team2.setPlayers(team1.getPlayers();
team1.setPlayers(null);
for (Player player : team2.getPlayers() {
   player.setTeam(team2);
}

Have you tried:

team2.setPlayers(team1.getPlayers();
team1.setPlayers(null);
for (Player player : team2.getPlayers() {
   player.setTeam(team2);
}
