/**
* Component to perform a bootstrap check of the alignment of the
* database, Lucene indexes and content store.
* <p>
* The algorithm is:
* <ul>
* <li>Get all stores from the NodeService</li>
* <li>Get each root node</li>
* <li>Perform a Lucene query for each root node</li>
* <li>Query Lucene for a small set of content nodes</li>
* <li>Get content readers for each node</li>
* </ul>
* If any of the steps fail then the bootstrap bean will fail, except if
* the indexes are marked for full recovery. In this case, the Lucene
* checks are not required as the indexes will be due for a rebuild.
