Redisearch 有没有办法获得搜索词的频率？例如，如果我在 Redisearch 中有以下文档

127.0.0.1:6379> FT.CREATE myIndex SCHEMA fileName TEXT SORTABLE content TEXT SORTABLE docId TAG SORTABLE NOINDEX
OK
127.0.0.1:6379> FT.ADD myIndex doc1 1.0 FIELDS fileName file1 content "lorem ipsum" docId doc1
OK
127.0.0.1:6379> FT.ADD myIndex doc2 1.0 FIELDS fileName file2 content "lorem ipsum lorem ipsum" docId doc2
OK
127.0.0.1:6379> FT.ADD myIndex doc3 1.0 FIELDS fileName file3 content "lorem ipsum lorem ipsum lorem ipsum" docId doc3
OK

有没有办法计算每个文档中“lorem”这个词的数量？

我尝试了这个聚合命令，但无法获得搜索词的频率。

127.0.0.1:6379> FT.AGGREGATE myIndex "lorem" GROUPBY 1 @content REDUCE COUNT 0 as frequency
1) (integer) 3
2) 1) "content"
   2) "lorem ipsum lorem ipsum"
   3) "frequency"
   4) "1"
3) 1) "content"
   2) "lorem ipsum"
   3) "frequency"
   4) "1"
4) 1) "content"
   2) "lorem ipsum lorem ipsum lorem ipsum"
   3) "frequency"
   4) "1"
