I have a question on the fields used by lucene search,

In the documentation it sais that you can only use String types for a field if you want it to be indexed. The problem is that the field i want to use is the content of a file. I used a blob and hibernates createblob in order to persist the file into the databse(MySQL, LONGTEXT) so i cant have it indexed. The question is how do i go about copying the content of the file into the database whilst being able to index that field. I also need the indexes to be automatically reindexed using the hibernate update add delete listeners.

I answered you on your other post, the DB type and the String representation in the Lucene index are 2 different things, the second is driven by the FieldBridge.
