-----------------------------------
Summary: Indexing: filter entries with a regular expression
Key: OAK-8934
URL: https://issues.apache.org/jira/browse/OAK-8934
Project: Jackrabbit Oak
Issue Type: Improvement
Components: indexing
Reporter: Thomas Mueller
Assignee: Thomas Mueller
We should provide a way to filter the index using a regular expression. For
example, only index nodes that contain a reference to another node. (Not a JCR
reference, but a reference within the value itself). For example, index a node
if one of the properties contains:
* /content/abc
* <html...> <a href="/content/abc">
* and so on
This will allow to run a query to find if /content/abc is referenced. The index
and the query will probably need to use a tag, and the cost of the index needs
to be high. Otherwise the query engine can't know when this index should be
used.
