Gus Heck commented on SOLR-14787:
---------------------------------
New Syntax with latest change (one less parameter, can check multiple tokens):
for payloads such as
{code:java}
"one|1.0 two|2.0 three|3.0"
{code}
This does not match
{code:java}
{!payload_check f=vals_dpf payloads='0.75 3' op='gt'}one two
{code}
but this does match
{code:java}
{!payload_check f=vals_dpf payloads='0.75 1.5' op='gt'}one two
{code}
> Inequality support in Payload Check query parser

> 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
> Assignee: Gus Heck
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h

> 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}
