blocks|key|3084170|text|在Redis中，无法搜索键的值。只有通过keys命令才能“找到”字符串。唯一的缺点是它搜索键名，而不是搜索值。解决这一问题的方法是将搜索字符串作为键，然后将所述键的值作为ID。我在自己的一侧使用了一个自动完成函数，我使用了另一个数据库，该数据库只包含带有ID作为值的搜索字符串。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3084171|entityMap^0|K|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

In Redis, there is no way to search the value of a key. The only way you can "find" a string, is via the <code>keys</code> command. The only downside is that it searches the key names, not the value. The way you can get around this is by having your search string as the key and then have the value of said key your ID. I use an autocompleate function on my side, and I use another database that just contains search strings with have an ID as a value.

You need to set up an index using sets or sorted sets that you write to when you save anything.

Redis itself does not support it. We have modified the source code of Redis so that it can support full-text search, string search, and some calculations of summation and average.

Project homepage: <a href="http://oncedb.com" rel="nofollow noreferrer">http://oncedb.com</a>

<h1>Full text search</h1>

OnceDB supports direct search, supports objects such as String and Hash,

<h2>Search string: search pattern operator value</h2>

Use the SEARCH command

<pre><code># Create data
set test1 'this is testing'
&gt; OK
set test2 'this is article'
&gt; OK

# Search data
search test* ~ article
1) test1
2) this is testing
3) test2
4) this is article
</code></pre>

Operator supports:

<pre><code>= Exact match
~ Partial match
&gt; &gt;= &lt; &lt;= Compare match
</code></pre>

<h2>Search hash: hsearch pattern field operator value ...</h2>

Use the hsearch command

There is no concept of "table" in redis. Generally, the key name using schema:id includes the table name and the primary key. For example, user:001 is a hash object with a user table and a primary key value of 001.

<pre><code># Create hash data
hmset user:001 name kris email c2u@live.cn gender male age 16
&gt; OK
hmset user:002 name sunny age 24
&gt; OK

# Search hash data
hsearch user:* age &gt; 18 name = *
1) user:002
2) 24
3) sunny
</code></pre>

<h2>Search ordered list(zset): zhsearch key from to schema field operator value ...</h2>

Use test:* or user:* pattern matching directly, because it will traverse all the keys, and the performance is low. zhsearch can search the corresponding primary key in an ordered list and specify the search scope.

In the above example, we store the primary key value of user into the *user ordered list, and the score is an integer about time

<pre><code>zadd *user 20020201 001 20020202 002
</code></pre>

Search for the first matching data (from 0 to 0)

<pre><code>zhsearch *user 0 0 user: age &gt; 10
1) -1
2) user:001
3) 16
</code></pre>

When using full-text search, the first parameter returned is always -1.

OnceDB does not change the data storage structure of Redis. Redis database files can be directly operated in OnceDB and then returned to Redis for use.

<h1>Index query</h1>

The performance of full-text search is poor. You can improve the performance by creating indexes.

OnceDB can choose to automatically create auxiliary indexes when data is modified.

You can try <a href="https://github.com/RediSearch/RediSearch" rel="nofollow noreferrer">RediSearch</a>. 
It's a Redis module that provides querying, secondary indexing, and full-text search for Redis.
It uses compressed, inverted indexes for fast indexing with a low memory footprint. 
It's indexes enhance Redis by providing exact-phrase matching, fuzzy search, and numeric filtering, among many other features.

I want an autocomplete feature. I have short descriptive strings on a 
property of a data type. I have a list of ids in redis for the 
datatype ordered by created date and I use the ids to set and get 
properties for the datatype as explained in the redis type 
documentation. I don't use hash tables. What's the best way to get a 
set of strings matching what's been typed into an autocomplete input 
box given this setup? Going through all ids and checking the property 
I want to search - for each keystroke seems like the wrong way to do 
this. 

EDIT:
In addition to the answers below, I've been shown this:
