Thomas Mueller commented on OAK-4637:
-------------------------------------
http://svn.apache.org/r1793097 (trunk)
Property "valuePattern" in the index definition, which is a regular expression.
The index is only used if the condition matches the pattern (for "in(list)", if
all entries in the list match). If a pattern is set, the index is not used for
"is not null" conditions.
> Property index: include/exclude key pattern list

> URL: https://issues.apache.org/jira/browse/OAK-4637
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: property-index
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Critical
> Fix For: 1.8
>
>
> In some cases, property indexes contain many nodes, and updating them can be
> slow. Right now we have filters for node and mixin types, path (include and
> exclude).
> An include and exclude list of values (patterns) would be useful. For example
> the property "status", if we only ever run queries with the condition "status
> = 'ACTIVE'", then nodes with status INACTIVE and DONE don't need to be
> indexed.
