こんにちは、「再フィルタリング」したい現在のクエリは次のとおりです。
START movie = node(*)
MATCH user-[:LIKE]->category-[:SIMILAR*0..3]-()<-[:TAGGED]->movie
WHERE user.name = "current_user"
WITH DISTINCT movie, user, category
RETURN user.name, category.name, ID(movie), movie.name
ORDER BY movie.name;

現在のクエリの後の様子は次のとおりです。
+--------------+----------------+-----------+-------------------------+
| user.name | category.name | ID(movie) | movie.name |
+--------------+----------------+-----------+-------------------------+
| current_user | c | 14 | movie_c_and_d_and_e |
| current_user | d | 14 | movie_c_and_d_and_e |
| current_user | e | 14 | movie_c_and_d_and_e |
| current_user | a | 9 | movie_of_a_and_b_and_b1 |
| current_user | b | 9 | movie_of_a_and_b_and_b1 |
| current_user | b | 10 | movie_of_b2_first |
| current_user | b | 11 | movie_of_b2_second |
| current_user | c | 12 | movie_of_c |
| current_user | d | 13 | movie_of_d_and_e |
| current_user | e | 13 | movie_of_d_and_e |
+--------------+----------------+-----------+-------------------------+
GROUP BY COUNT(sugg) AS category_countこれを抽出したい：
+--------------+----------------+-----------+-------------------------+
| user.name | category_count | ID(movie) | movie.name |
+--------------+----------------+-----------+-------------------------+
| current_user | 3 | 14 | movie_c_and_d_and_e |
| current_user | 2 | 9 | movie_of_a_and_b_and_b1 |
| current_user | 2 | 13 | movie_of_d_and_e |
| current_user | 1 | 10 | movie_of_b2_first |
| current_user | 1 | 11 | movie_of_b2_second |
| current_user | 1 | 12 | movie_of_c |
+--------------+----------------+-----------+-------------------------+
どうすればこれを達成できますか?

作業結果は次のとおりです（デモ付き：http://tinyurl.com/cywlycc）：
START movie = node(*)
MATCH user-[:LIKE]->category-[:SIMILAR*0..3]-()<-[:TAGGED]->movie
WHERE user.name = "current_user"
WITH DISTINCT movie, category WITH COUNT(movie) AS category_count, movie, collect(category.name) as categorized
RETURN category_count, ID(movie), movie.name, categorized
ORDER BY category_count DESC;
