PostFilter

All Known Implementing Classes:

AbstractReRankQuery, AnalyticsQuery, CollapsingQParserPlugin.CollapsingPostFilter, ExportQParserPlugin.ExportQuery, ExtendedQueryBase, FilterQuery, FunctionRangeQuery, RankQuery, SolrRangeQuery, WrappedQuery
```
public interface ExtendedQuery
```
The ExtendedQuery interface provides extra metadata to a query. Implementations of ExtendedQuery must also extend Query.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`boolean`	`getCache()`	Should this query be cached in the query cache or filter cache.
`int`	`getCost()`	Returns the cost of this query, used to order checking of filters that are not cached.
`default org.apache.lucene.search.Query`	`getCostAppliedQuery()`	Returns this Query, applying `QueryUtils.makeQueryable(Query)` and maybe wrapping it to apply the `getCost()` if it's above zero.
`void`	`setCache(boolean cache)`
`void`	`setCost(int cost)`

- Method Detail
  - getCache
```
boolean getCache()
```
    Should this query be cached in the query cache or filter cache.
  - setCache
```
void setCache(boolean cache)
```
  - getCost
```
int getCost()
```
    Returns the cost of this query, used to order checking of filters that are not cached. If getCache()==false && getCost()>=100 && this instanceof PostFilter, then the PostFilter interface will be used for filtering. Otherwise, for smaller costs, this cost will be used for TwoPhaseIterator.matchCost().
  - setCost
```
void setCost(int cost)
```
  - getCostAppliedQuery
```
default org.apache.lucene.search.Query getCostAppliedQuery()
```
    Returns this Query, applying QueryUtils.makeQueryable(Query) and maybe wrapping it to apply the getCost() if it's above zero. Subclasses may customize this if the query internally applies the configurable cost on the underlying TwoPhaseIterator.matchCost().
