When indexing Java package names for search, consider indexing the whole package name

Description

In 10.8 we started indexing tokens between periods here. I would like to propose indexing the whole package name.

Proposal

The proposal consists of indexing both the tokens between the periods and also the whole package name. For instance, "com.gitlab.git" would generate the tokens "com", "gitlab", "git" and also "com.gitlab.git".
