Subject [jira] [Commented] (CASSANDRA-11067) Improve SASI syntax
Date Thu, 04 Feb 2016 16:28:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15132531#comment-15132531

Jack Krupansky commented on CASSANDRA-11067:
--------------------------------------------

Clarification question: Will SASI apply the analyzer to the LIKE string?

Then... what will happen if that analysis produces more than one term? In Solr land that is
expected and the semantics is phrase query. What will SASI do? Will it be an error or be treated
as a list of AND terms?

> I think everyone agrees that a LIKE operator would be ideal, but that's probably not
in scope for an initial 3.4 release.
> Still, I'm uncomfortable with the initial approach of overloading = to mean "satisfies
index expression."  The problem is that it will be very difficult to back out of this behavior
once people are using it.
> I propose adding a new operator in the interim instead.  Call it MATCHES, maybe.  With
the exact same behavior that SASI currently exposes, just with a separate operator rather
than being rolled into =.
