By the way, picky does something similar and has a redis backend as well:

The website also explains the difference to full-text-indexers like SOLR and elasticsearch.
I could see such solutions used in cases where:

1. you are already using Redis for some other part of the application

2. you don't want yet to have Lucene/Solr/ElasticSearch

3. you don't need to support too advanced searches

On the other hand while building such a library could be a good learning exercise, I think that before using it in an application you should look for other already existing libraries and try to collaborate with the original authors.

Two questions pop in my mind. How does it compare to Solr ? What's wrong with Solr ?
After skimming the doc (in Chinese), here're my two answers, Sir:

* It offers way fewer functionalities than does Solr

* There is nothing wrong with Solr, just that someone wants to try something new that fits his/her needs
