RediSearch | A query and indexing engine for Redis, providing secondary indexing, full-text search, vector simila | Search Engine library

I am using redis_OM in order to make it easier to do aggregations using redisearch module. The thing is that I want to upload some data to redis everyday without keeping the one uploaded the day before, that is to say, I want either to make the old data expire or overwrite it with the new one.

I am doing it with the example of the Redis documentation and redis cloud. This is my model:

I'm using the modules RedisJSON and RediSearch together to perform search queries on JSON data. Given a json list like this:

{"email": "test1@example.com", "is_checked": 1}

I do:

I have two apps in go language. user_management app, which I run (docker-compose up --build) first, then I run(docker-compose up --build) sport_app. sport_app is dependent from user_management app.

sport_app Dockerfile file as below.

Is there a way to get a total results count when calling Aggregate function?

Note that I'm not using Aggregate function to aggregate results, but as an advanced search query, because Search function does not allow to sort by multiple fields.

RediSearch returns total documents matched count, but I can't find a way to get this number using NRediSearch library.

I have installed the plugin MacFJA/php-redisearch using the following command

composer require macfja/redisearch

Issue:

How can I sort results, first by some numeric field (for example by price) then by distance when using GEOFILTER in RediSearch?

I am new to Redis and Redisearch. I want to create an autocomplete using redis in flask app.

Below is what I have tried so far,

autocomplete.py:

I use Jredisearch(com.redislabs:jredisearch:2.0.0) to store data in an Index. I want to add a prefix while creating the Index. I am able to add prefix using the below Redisearch command FT.CREATE MyIndex ON HASH PREFIX 1 doc: SCHEMA name TEXT

But not able to find options for the same when writing in Java. I use the following code in Java, client.createIndex(schema, Client.IndexOptions.defaultOptions());

Could anyone suggest how do we add Prefix when using Jredisearch?

For example: consider that a hash (lets call it Event) has two searchable properties: user_id (num) and name (text).

However, whenever I need to filter events by name I aways have the user_id at hand. So I am wondering if it makes sense to have one index of events per user instead of one big index of events for all users.

From my basic knowledge with Redis and RediSearch:

• One index for all events of all users:
  • Prefix: "events:"
  • Key examples: events:123, events:456
  • Pros: easier.
  • Cons: whenever I need to search for events of name "foo" and user_id 100 RediSearch needs to find a block of events using the user_id and then filter the name. The hash needs to be in the same shard or use the coordinator.
• One index per user for its events:
  • Prefixes: "events:%USER_ID%:", ie "events:789" where 789 is an user id
  • Key examples: events:789:123
  • Pros: Smaller indexes for better performance and can be easily distributed.
  • Cons: harder to maintain. If there are 1mi users we have 1mi indexes, dunno if this is a problem or not.
