Define a hidden search request on a form to apply criteria, columns, sorting, or aggregations invisible to users.

The ComponentSearchPresenter object accepts a hiddenRequest property with a com.flower.docs.domain.search.SearchRequest class bean. This request allows you to:

  • add hidden criteria
  • configure the columns to be displayed
  • set default sorting
  • set the number of results to be displayed
  • configure aggregations for tree-view display

Example

<bean id="monFormulaire" class="com.flower.docs.gui.client.search.ComponentSearchPresenter"
		scope="prototype">
		<!-- ... -->
		<property name="hiddenRequest">
			<bean class="com.flower.docs.domain.search.SearchRequest">
				<property name="selectClause">
					<bean class="com.flower.docs.domain.search.SelectClause">
						<property name="fields">
							<list>
								<!-- Columns to display-->
								<value>name</value>
								<value>TypeCourrier</value>
							</list>
						</property>
					</bean>
				</property>
				<property name="filterClauses">
					<list>
						<bean class="com.flower.docs.domain.search.AndClause">
							<!-- Hidden criteria -->
							<property name="criteria">
								<list>
									<bean class="com.flower.docs.domain.search.Criterion">
										<property name="name" value="classid" />
										<property name="type">
											<value type="com.flower.docs.domain.search.Types">STRING</value>
										</property>
										<property name="operator">
											<value type="com.flower.docs.domain.search.Operators">EQUALS_TO</value>
										</property>
										<property name="values">
											<list>
												<value>CourrierEntrant</value>
											</list>
										</property>
									</bean>
								</list>
							</property>
						</bean>
					</list>
				</property>
				<!-- Search results to display -->
				<property name="max" value="42" />
			</bean>
		</property>
		<!-- ... -->
	</bean>

Sorting

The default sort order of results is configured using the orderClauses property on the SearchRequest object. Each OrderClause defines a field name and a sort direction.

<property name="orderClauses">
    <list>
        <bean class="com.flower.docs.domain.search.OrderClause">
            <property name="name" value="creationDate" />
            <property name="ascending" value="false" />
        </bean>
    </list>
</property>

Multiple sort clauses can be combined. They are applied in order of declaration.

Aggregation

An aggregation groups search results by field values, displaying them as a tree structure. When a bucket is selected, the search is filtered to match that bucket's criteria.

Aggregations are configured using the aggregation property on the SearchRequest object with a FieldAggregation bean. Nested aggregations create multi-level grouping.

<property name="aggregation">
    <bean class="com.flower.docs.domain.search.FieldAggregation">
        <property name="nested">
            <list>
                <bean class="com.flower.docs.domain.search.FieldAggregation">
                    <property name="field" value="TypeCourrier" />
                </bean>
                <bean class="com.flower.docs.domain.search.FieldAggregation">
                    <property name="field" value="CanalEntree" />
                </bean>
            </list>
        </property>
    </bean>
</property>

Hidden columns

To retrieve tag values via the selectClause without displaying them as visible columns, use the hiddenColumns property on the ComponentSearchPresenter. See Search results for details.

info
  • We recommend using the notion of hidden requests to simplify access to components, rather than to secure access to them.
  • Add the ADD_FILTERS_TO_SELECT criterion with the true value in the request contexts to display the criteria filled in as columns.
