Thomas Mueller updated OAK-401:
-------------------------------
Component/s: query
> QueryIndex cost output
> ----------------------
>
> Key: OAK-401
> URL: https://issues.apache.org/jira/browse/OAK-401
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, query
> Reporter: Alex Parvulescu
>
> Currently all (both) QueryIndex impl output a constant 1.0 cost value.
> This makes for a difficult choice on the QueryEngine side of things, which
> currently keeps the first index it sees.
> For example a lucene can trump a propertyindex in a uuid resolve query, even
> though it shouldn't.
