             Summary: Inequality support in Payload Check query parser
                 Key: SOLR-14787
                 URL: https://issues.apache.org/jira/browse/SOLR-14787
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Kevin Watters


The goal of this ticket/pull request is to support a richer set of matching and filtering based on term payloads.  This patch extends the PayloadCheckQueryParser to add a new local param for "op"

The value of OP could be one of the following
 * gt - greater than
 * gte - greater than or equal
 * lt - less than
 * lte - less than or equal

default value for "op" if not specified is to be the current behavior of equals.

Additionally to the operation you can specify a threshold local parameter

This will provide the ability to search for the term "cat" so long as the payload has a value of greater than 0.75.  

One use case is to classify a document into various categories with an associated confidence or probability that the classification is correct.  That can be indexed into a delimited payload field.  The searches can find and match documents that were tagged with the "cat" category with a confidence of greater than 0.5.

Example Document
{code:java}
{ 
  "id":"doc_1",
  "classifications_payload":["cat|0.75 dog|2.0"]
}
{code}
Example Syntax
{code:java}
{!payload_check f=classifications_payload payloads='1' op='gt' threshold='0.5'}cat  {code}
