Solr块加入父查询解析器范围查询错误

Question

I am using Solr 6.1.0, and I'm indexing Parent-Child data into Solr.

When I do my query, I use the Block Join Parent Query Parser, to return only the parent's records, and not any of the child records, even though there might be a match in the child record.

However, I am not able to do the range query for the child record. For example, if I search with this query q= +title:join +{!parent which="content_type:parentDocument"}range_f:[2 TO 8]

I will get the following error:

{ 
  "responseHeader":{
    "zkConnected":true,
    "status":400,
    "QTime":3},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.parser.ParseException"],
    "msg":"org.apache.solr.search.SyntaxError: Cannot parse 'range_f:[2': Encountered \"<EOF>\" at line 1, column 18.\r\nWas expecting one of:\r\n    \"TO\" ...\r\n    <RANGE_QUOTED> ...\r\n    <RANGE_GOOP> ...\r\n    ",
    "code":400}}

What could be the issue here?

Answer 1

Try with:

q= +title:join +_query:"{!parent which=\\"content_type:parentDocument\\"}range_f:[2 TO 8]"

Answer 2

You cannot have any spaces before the join query so this would work

{!parent which="content_type:parentDocument"}range_f:[2 TO 8]

One way to get around this is to move the range query to the fq parameter instead of the q parameter.
