如何在solrconfig.xml中设置SOLR参数替换

因此,根据这个http://yonik.com/solr-query-parameter-substitution/,可以在solrconfig中设置一个搜索处理程序

request handler defaults,appends,and invariants configured for the
handler may reference request parameters

我有以下查询适用于卷曲

curl http://localhost:7997/solr/vb_popbio/select -d 'q=*:*&fq=bundle:pop_sample_phenotype AND phenotype_type_s:"insecticide%20resistance"
&rows=0&wt=json&json.nl=map&indent=true
&fq=phenotype_value_type_s:${PFIELD}&
&PGAP=5&PSTART=0&PEND=101&PFIELD="mortality rate"&
json.facet = {
            pmean: "avg(phenotype_value_f)",pperc: "percentile(phenotype_value_f,5,25,50,75,95)",pmin: "min(phenotype_value_f)",pmax: "max(phenotype_value_f)",denplot : {
                type : range,field : phenotype_value_f,gap : ${PGAP:0.1},start: ${PSTART:0},end: ${PEND:1}
            }
    }'

我已将此查询转换为solrconfig.xml中的搜索处理程序配置,因此用户只需提供PFIELD,PGAP,PSTART和PEND参数.以下是处理程序的配置外观

<!--A request handler to serve data for violin plots (limited to IR assays)-->
<requestHandler name="/irViolin" class="solr.SearchHandler">
    <!-- default values for query parameters can be specified,these
         will be overridden by parameters in the request
      -->
    <lst name="defaults">
        <str name="echoParams">explicit</str>
        <int name="rows">0</int>
        <str name="df">text</str>
        <str name="wt">json</str>
        <str name="json.nl">map</str>
        <str name="json.facet">{
            pmean: "avg(phenotype_value_f)",denplot : {
            type : range,gap: ${PGAP:0.1},end: ${PEND:1}
            }
            }
        </str>
    </lst>
    <lst name="appends">
        <str name="fq">bundle:pop_sample_phenotype</str>
        <str name="fq">phenotype_type_s:"insecticide resistance"</str>
        <str name="fq">has_geodata:true</str>
        <str name="fq">phenotype_value_type_s:${PFIELD:"mortality rate"}</str>

    </lst>
    <lst name="invariants">
    </lst>

</requestHandler>

请注意,我为所有参数提供了默认值,否则SOLR将无法加载配置.问题是使用这样的查询

curl http://localhost:7997/solr/vb_popbio/irViolin?q=*:*&
    &PGAP=5&PSTART=0&PEND=101&PFIELD="mortality rate"

不管用. SOLR将正确读取请求参数(我可以在调试输出上看到它们),但会忽略它们并使用配置中的默认值.

SOLR版本是5.2.1.

我尝试将配置参数移动到默认值,追加或不变量,但没有任何工作.经过2天的研究,我几乎已经准备好放弃,而是在运行中构建整个查询.

任何帮助将不胜感激.

非常感谢
