You can search using multiple conditions. You define the type of search as follows:
• ALL of the conditions below are met — This is the Boolean "AND" operator. The search returns
assets that match all conditions. Only conditions with values (conditions that are not blank) are
included in the search.
• ANY of the conditions below are met — This is the Boolean "OR" operator. The search returns
assets that match any of the conditions. Only conditions with values (conditions that are not
blank) are included in the search.
• Custom — You can enter text to create a custom expression using Boolean operators.
In your custom expression, you use the condition numbers (1, 2, 3, 4, etc) to represent the condition
on which you are searching. For example, if you have configured condition 1 as "Asset Name
is basketball" and condition 2 as "Asset Created is Today", then entering custom expression "1
AND 2" finds assets named basketball created today.
The "OR" and "AND" operators are at the same precedence, so for complex expression you use
parentheses to group relationships. The following are examples of complex expressions:
• (1 AND 2) OR (1 AND 3)
• ((1 AND 4) OR 3) AND ((2 OR 4) AND 3)
When entering a custom expression, you must reference only conditions with values (conditions
that are not blank).
You can use advanced query syntax in the Advanced Search tool. When you create a "contains"
condition that searches a text field, you can enter text with advanced query syntax to search that
field. The following is an example of this type of condition:
• Name | contains | guitar NOT rock
In this way a search in the Simple Search tool is equivalent to a "contains" search that searches
multiple text fields by default. For a simple search you can enter text with advanced query syntax.
Assets with names, tags, descriptions, comments, marker text, or custom text data that match the
search are returned.
For an extended application of boolean logic in the Advanced Search tool, you can create multiple
conditions that search text fields, each of which use advanced query syntax. Then you can combine
those conditions as a custom expression.
