   > I have no idea for how to support `LIKE`, any suggestions?
   My idea now is to divide the content into groups of X characters, then 
encrypt each group separately, and then splice them together for storage. When 
querying, repeat the steps of grouping encryption, and then query; At present, 
there are two points to be controlled in this method: first, the encrypted 
characters will be relatively long. This method uses storage space to realize 
this requirement; Second, we need to control the size of variable x, which 
should not be too short. Too long will also affect the search experience
