Keyword Expressions

Keyword expressions allow you to construct your own complex queries in Advanced Search, letting you combine multiple keyword-based search terms that follow this basic syntax: search_field:phrase. For example, to search for all messages containing "Alert" or "Notification" anywhere in the Subject field,

1. Click the BASIC > Search tab, and then click Advanced.
2. Select Email as the item type, and then select Keyword Expression as the parameter.
3. In the text field, type: subject:"Alert" OR subject:"Notification"
   
4. Click Search to return all matching search results.

Table 1. Commonly used search_field values.

You may specify other search_field values as long as the correct name for the field is used. Consult Barracuda Networks Technical Support if you are unsure of the exact syntax.

The phrase can only contain a single item. However, that one item can be any one of the following:

• a single Text-based string;
• a single Integer number-based string;
• a single Wildcarded string;
• a single Domain-based string (for to and from search_field only);

• a single compound search string created by combining multiple strings with the keywords AND and OR, and grouping the phrases with parentheses to control the logic.

  Important

  When creating compound search strings, the keywords 'AND' and 'OR' must be capitalized.

Proximity Syntax Form

For the keyword proximity syntax form, each keyword must be in a single Text-based string. Enter the keyword proximity syntax as search_field:"keyword keyword"~NumericValue, where search_field is the part of the email to search through.

Fuzzy Search Syntax Form

Fuzzy search allows you to find words that are similar to a specified search term. For the fuzzy search syntax, enter a single keyword followed by the tilde (~). For the fuzzy search syntax form, the keyword must be in a single Text-based string.
