Description

Enterprise Vault (EV) Compliance Accelerator (CA) Searches are primarily designed to Search for messages based on Department Tagging of Monitored Employees. They can also Search based on terms listed in the Subject field of a message and/or in the Content of a message. Discovery Accelerator (DA) Searches are designed to Search based on the Criteria as entered in the Search. In addition for messages based on the terms and other Criteria listed in the Search, Searches can exclude messages based on terms listed in the Subject and/or Content fields of a message. The syntax of such exclusion Searches is common to CA and DA. Here is an example excerpt from the DA Help and the Administrator's Guide:

- Place the minus sign (-) in front of a word or phrase to connect it to every other word or phrase on the line with a Boolean AND NOT condition. This sign instructs Discovery Accelerator to exclude from the result set those results that match the other search criteria and contain the excluded term. For example, the following search string means "(server AND NOT test) OR (group AND NOT test) OR (cluster AND NOT test)":

[Any Of] server group -test cluster

In the following example, the search string means "(server AND cluster AND (group AND NOT test))":

[All Of] server
cluster
group -test

A search term cannot comprise an excluded word or phrase only. When you specify such words or phrases, you must also specify a positive word or phrase that you want to appear in the search results.

- A search term cannot start with any of the following characters on any line:

= + - @

For example, "server -cluster" is a valid search term but "-cluster server" is not.

Syntax note

To perform an exclusion Search, a term must be preceded by a minus sign, or dash. Such a minus sign or dash is also known as an 'en dash'. This is the shorter of the two available dashes and is used by simple text editors, such as Microsoft Notepad. Complex text editors, such as Microsoft Word, use the longer of the two available dashes, also known as an 'em dash'. The use of 'en' or 'em' refers to the length of the smaller dash being approximately the same as the width of the letter 'n', and the length of the longer dash being approximately the same as the width of the letter 'm'. An 'en dash' is the correct dash to use when entering an exclusion. The 'em dash' will be seen as a searchable character and will not provide the expected Search results. Therefore, it is always recommended to enter the Search criteria directly in the Search pane or to use a simple text editor to create the criteria.

Notes

- A Search Criteria cannot list exclusion terms/phrases only. There must be at least one inclusion term/phrase on the same line and at the beginning of the line. Attempting to only use exclusions without any inclusions will result in the warning message:

'A search term cannot compromise an excluded word or phrase only. When you specify such words or phrases, you must also specify a positive word of phrase that you want to appear in the search results.'

- Search terms on a single line are considered as a phrase by CA. This is the major difference from DA and is the most important to remember. It is not necessary to enclose terms within quotation marks to denote them as a phrase in CA but it is necessary to enclose terms within quotation marks in DA. As long as there are terms on a single line, a CA Search will consider them to be a phrase.
