Bug Description

Lucene allows to pass FieldSelector class that can be used to select which fields are actually loaded from the disk. This needs to be passed as argument to Searcher.doc(int, FieldSelector).

Maybe this could be supported via a parameter to the projection method :

  query.list(FieldSelector)

Additionally this could also be supported via a list of fields to be loaded as Querydsl expressions :

  query.list(prop1, prop2, prop3);

The second approach would support only the LOAD and NO_LOAD options

I think the first version is anyway needed, the second could be nice option.

Support has been added :

    /**
     * Set the given FieldSelector to the query
     *
     * @param fieldSelector
     * @return
     */
    public Q load(FieldSelector fieldSelector);

    /**
     * Load only the fields of the given paths
     *
     * @param paths
     * @return
     */
    @SuppressWarnings("unchecked")
    public Q load(Path<?>... paths);
