Zimbra Mailbox Server > Index Store

Index Store
The index and search technology is provided through Apache Lucene. Each email message and attachment is automatically indexed when the message arrives. An index file is associated with each account. Index files are in opt/zimbra/index.
The tokenizing and indexing process is not configurable by administrators or users.
Message Tokenization
The process is as follows:
1.
The Zimbra MTA routes the incoming email to the VMware Zimbra Collaboration Server mailbox server that contains the account’s mailbox.
2.
The mailbox server parses the message, including the header, the body, and all readable file attachments such as PDF files or Microsoft Word documents, in order to tokenize the words.
3.
Note:
Tokenization is the method for indexing by each word. Certain common patterns, such as phone numbers, email addresses, and domain names are tokenized as shown in the Message Tokenization figure.
