[jira] [Created] (SOLR-7218) constant score query syntax
Yonik Seeley created SOLR-7218:
----------------------------------
Summary: constant score query syntax
Key: SOLR-7218
URL: https://issues.apache.org/jira/browse/SOLR-7218
Project: Solr
Issue Type: New Feature
Reporter: Yonik Seeley
A ConstantScoreQuery is like a boosted query, but it produces the same score for every document that matches the query. The score produced is equal to the query boost. The ^= operator is used to turn any query clause into a ConstantScoreQuery.
Constant Score Query Examples:
{code}
+color:blue^=1 text:shoes
(inStock:true text:heliosearch)^=100 native code faceting
{code}
Syntax rational: since boosting (multiplication) is term^value, the syntax for having a constant score can be term^=value
