With object-based queries, you specify a query expression in the query request entry. Query expressions have this format:
[+|-]criterion [[+|-]criterion]...
In this expression, [+|-] is an optional Boolean operator and criterion is one of:
- A single text-based or property-based criterion.
- One or more criteria in parentheses, in this format:
([+|-]criterion [[+|-]criterion]...)
In this expression, criterion can be a single criterion or one or more criteria in parentheses.
For example, here is one possible query expression:
-(namespace:"finance.europe") +(retention:0 index:1)
Query expressions can contain only valid UTF-8 characters.
Tip: You can use the Metadata Query Engine Console to generate query expressions. To do this, construct a query on the Structured Query page and then click the Show as advanced query link. The resulting advanced query can be used as a query expression in an object-based query request.
