I wonder there is a proper way to solr documents with sync database records. I usually have problems: there is solr documents while there are no database records referent by solr. It seems some db records has been deleted, but no trigger has been to update solr. I want to write a rake task to remove documents in solr that run periodically.
Any suggestions?

Yes, there is one.
You have to use the DataImportHandler with the delta import feature.
Basically, you specify a query that updates only the rows that have been modified, instead of rebuilding the whole index. Here’s an example.
Otherwise you can add a feature in your application that simply trigger the removal of the documents via HTTP in both your DB and in your index.
