# Configuring search
|
|

{! backend/administration/CLI_tasks/general_cli_task_info.include !}
|
|
|
|
## Built-in search
|
|
|
|
To use built-in search that has no external dependencies, set the search module to `Pleroma.Activity`:
|
|
|
|
> config :pleroma, Pleroma.Search, module: Pleroma.Activity
|
|
|
|
While it has no external dependencies, it has problems with performance and relevancy.
|
|
|
|
## Meilisearch
|
|
|
|
To use [meilisearch](https://www.meilisearch.com/), set the search module to `Pleroma.Search.Meilisearch`:
|
|
|
|
> config :pleroma, Pleroma.Search, module: Pleroma.Search.Meilisearch
|
|
|
|
You then need to set the address of the meilisearch instance, and optionally the private key for authentication.
|
|
|
|
> config :pleroma, Pleroma.Search.Meilisearch,
|
|
> url: "http://127.0.0.1:7700/",
|
|
> private_key: "private key"
|
|
|
|
Information about setting up meilisearch can be found in the
|
|
[official documentation](https://docs.meilisearch.com/learn/getting_started/installation.html).
|
|
You probably want to start it with `MEILI_NO_ANALYTICS=true` and `MEILI_NO_CENTRY=true` environment variables,
|
|
to disable analytics.
|
|
|
|
### Private key authentication (optional)
|
|
|
|
To set the private key, use the `MEILI_MASTER_KEY` environment variable when starting. After setting the _master key_,
|
|
you have to get the _private key_, which is actually used for authentication.
|
|
|
|
=== "OTP"
|
|
```sh
|
|
./bin/pleroma_ctl search.meilisearch show-private-key <your master key here>
|
|
```
|
|
|
|
=== "From Source"
|
|
```sh
|
|
mix pleroma.search.meilisearch show-private-key <your master key here>
|
|
```
|
|
|
|
This is the key you actually put into your configuration file.
|
|
|
|
### Initial indexing
|
|
|
|
After setting up the configuration, you'll want to index all of your already existsing posts. Only public posts are indexed. You'll only
|
|
have to do it one time, but it might take a while, depending on the amount of posts your instance has seen. This is also a fairly RAM
|
|
consuming process for `meilisearch`, and it will take a lot of RAM when running if you have a lot of posts (seems to be around 5G for ~1.2
|
|
million posts while idle and up to 7G while indexing initially, but your experience may be different).
|
|
|
|
To start te initial indexing, run the `index` command:
|
|
|
|
=== "OTP"
|
|
```sh
|
|
./bin/pleroma_ctl search.meilisearch index
|
|
```
|
|
|
|
=== "From Source"
|
|
```sh
|
|
mix pleroma.search.meilisearch index
|
|
```
|
|
|
|
This will show you the total amount of posts to index, and then show you the amount of posts indexed currently, until the numbers eventually
|
|
become the same. The posts are indexed in big batches and meilisearch will take some time to actually index them, even after you have
|
|
inserted all the posts into it. Depending on the amount of posts, this may be as long as several hours. To get information about the status
|
|
of indexing and how many posts have actually been indexed, use the `stats` command:
|
|
|
|
=== "OTP"
|
|
```sh
|
|
./bin/pleroma_ctl search.meilisearch stats
|
|
```
|
|
|
|
=== "From Source"
|
|
```sh
|
|
mix pleroma.search.meilisearch stats
|
|
```
|
|
|
|
### Clearing the index
|
|
|
|
In case you need to clear the index (for example, to re-index from scratch, if that needs to happen for some reason), you can
|
|
use the `clear` command:
|
|
|
|
=== "OTP"
|
|
```sh
|
|
./bin/pleroma_ctl search.meilisearch clear
|
|
```
|
|
|
|
=== "From Source"
|
|
```sh
|
|
mix pleroma.search.meilisearch clear
|
|
```
|
|
|
|
This will clear **all** the posts from the search index. Note, that deleted posts are also removed from index by the instance itself, so
|
|
there is no need to actually clear the whole index, unless you want **all** of it gone. That said, the index does not hold any information
|
|
that cannot be re-created from the database, it should also generally be a lot smaller than the size of your database. Still, the size
|
|
depends on the amount of text in posts.
