Karel Vervaeke commented on JBPM-2505:
--------------------------------------

If anyone is interested in this, DaisyCMS is offering this kind of thing already (on top of JBPM 3.2)

Here's a link to get you started:
http://dev.outerthought.org/svn/outerthought_daisy/trunk/daisy/services/workflow/server-impl/src/main/java/org/outerj/daisy/workflow/serverimpl/query/QueryGenerator.java

I don't use the functionality enough to know how well it scales, but I'm sure that it works well enough for most small to medium scale instances. (We never had the need to add indices). The amount of variables included in your query will be an important factor.

> Currently, there's no way of searching for process instances that contain variables set to a given value.
> Sometimes, there's no way of assigning a process instance key when starting a process, so we need to search for processes using values stored in some of the variables...
