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}
