Hello.
I am using in my project "Hibernate Search". Everything works fine, but I have a one question.
Data in my project stored in a specific format: "text [hidden words]". Hidden words aren't shown to users.
Can I not index the text, which correspond to a particular pattern(using regex for example)?

Hi,
you can do that in two ways:

1) (simpler) create a custom StringBridge and register it on the fields you need to "filter": See also http://docs.jboss.org/hibernate/search/4.1/reference/en-US/html_single/#d0e4037;
your implementation should just remove the [...] part.

2) (better reusable and better performance) create a custom Analyzer. For some examples I'd suggest to look into the Lucene source code as there are many Analyzers in it.
