IMatchQuery<T>
Deprecated.
If possible, use one of the predefined queries in
QueryUtil or
use the QueryUtil.createMatchQuery(String, Object...)
to create a custom expression based query. If the query cannot be expressed using
the p2QL, then use a predefined or custom expression query as a first filter
(in worst case, use QueryUtil.createIUAnyQuery() ) and then provide further filtering
like so:for(iter = queryable.query(someExpressionQuery).iterator(); iter.hasNext();) { // do your match here } |
