    a list of lists of query result. Each list corresponds to a source text (in the same order)
  - batchQuery
```
List<List<QueryResult>> batchQuery(List<TextFragment> fragments)

    Starts a batch query for a given list of TextFragments. Some IQuery implementations are significantly faster when a using batch query.
    Note that batchQuery does not use hasNext and next methods. Callers must use the returned list directly.
    
    Parameters:
    
    fragments - list of the text fragments to translate.
    
    Returns:
    
    a list of lists of query result. Each list corresponds to a source text (in the same order)
  - hasNext
```
boolean hasNext()

    Indicates of there is a hit available.
    
    Specified by:
    
    hasNext in interface Iterator<QueryResult>

    Gets the next hit for the last query.
    
    Specified by:
    
    next in interface Iterator<QueryResult>
    
    Returns:
    
    A QueryResult object that holds the source and target text of the hit, or null if there is no more hit.
  - setRootDirectory
```
void setRootDirectory(String rootDir)
```
    Sets the root directory that may be used to replace the available ${rootDir} in the parameters of this object.
    
    Parameters:
    
    rootDir - the root directory.
  - setWeight
```
void setWeight(int weight)
```
    Set the relative weight of this IQuery connector as compared to other connectors. Used to set QueryResult.weight.
    
    Parameters:
    
    weight - the new relative weight.
  - getWeight
```
int getWeight()
```
    Get the weight for this connector.
    
    Returns:
    
    the weight for this connector
  - setNoQueryThreshold
```
void setNoQueryThreshold(int noQueryThreshold)
```
    Sets the threshold for when to avoid executing a query.
    If the entry to leverage has already one candidate with a score equals or above this value, no query is performed. Use 101 to always allow the query.
    
    Parameters:
    
    noQueryThreshold - no-query threshold (a value between 0 and 101).
  - getNoQueryThreshold
```
int getNoQueryThreshold()
