Register a weighted fuzzy search endpoint for Strapi Headless CMS you can add your content types to in no time.
Uses fuzzysort under the hood: Simple, quick and easy. No need to worry about setting up an instance for a complex search engine.

Strapi Version >= v4.11.4
For compatibility with older Strapi versions please use older Versions of this package (<= 1.11.2 and <= 2.0.3)
Enable the fuzzy-search plugin in the ./config/plugins.js of your Strapi project.
Make sure to set the appropriate permissions for the search route in the Permissions tab of the Users & Permission Plugin for the role to be able to access the search route.
Mandatory settings are marked with *.
The plugin requires several configurations to be set in the .config/plugins.js file of your Strapi project to work.
| Key | Type | Notes |
|---|---|---|
| contentTypes* | Array of Objects | List the content types you want to register for fuzzysort. Each object requires the uid: string and modelName: string to be set for a content type |
| transliterate | boolean | If this is set to true the search will additionally run against transliterated versions of the content for the keys specified in the keys array for a given content type. E.g. 你好 will match for ni hao. Note that activating this feature for a content type comes at a performance cost and may increase the response time. |
The fuzzysortOptions allow for some finetuning of fuzzysorts searching algorithm to your needs.
| Key | Type | Notes |
|---|---|---|
| characterLimit | int (positive) | Limits the length of characters the algorithm is searching through for any string of the content type |
| threshold | int (negative) | Sets the threshold for the score of the entries that will be returned. The lower, the "fuzzier" the results. |
| limit | int (positive) | Limits the amount of entries returned from the search |
| keys* | array of objects | Lists the fields of the models the algorithm should search (name: string) and a factor to weight them by weight: int. The higher the weight, the higher a match for a given field will be evaluated for a content type. |

enabled: true,

modelName: "author",
transliterate: true,

},
// ...
});A high characterLimit, limit, a low threshold (the lower the value the more matches) as well as setting transliterate: true all hamper the performance of the search algorithm. We recommend that you start out with a characterLimit: 500, threshold: -1000, limit: 15 and work your way from there. The characterLimit especially can be quite delicate, so make sure to test every scenario when dialing in it's value.
Hitting the /api/fuzzy-search/search?query=<your-query-string> will return an array of matched entries for each content type registered in the config. If no match could be found an empty array will be returned. The endpoint accepts an optional locale=<your-locale> query as well.
Alternatively (and if the graphql plugin is installed), a search query is registered that accepts query: String! and locale: String (optional) as arguments. If set, the locale parameter will be used as a default for all queried content types. If you'd rather filter the content types by local on an individual level, pass the locale to the content type as a filter parameter.
IMPORTANT: Please not that in order to query for the locale of the content types via the locale parameter, localization must be enabled for the content types.
await fetch(`${API_URL}/api/fuzzy-search/search?query=deresh&locale=en`);
// GET /api/fuzzy-search/search?query=deresh&locale=enquery {
search(query: "deresh", locale: "en") {
authors {
data {
attributes {
name
}
}
}
books {
data {
attributes {
title
description
}
}
}
}
}IMPORTANT: Please note that as of now published as well as unpublished entries will be returned by default. Modify this behavior by passing a filter to the query.

}The endpoint accepts query parameters in line with Strapis pagination by page parameters. The difference being that the pagination is scoped for the content types individually.
Important: Please note that if pagination parameters are passed for a content type, it's data will now be available under the key data, whereas the pagination meta data can be found under the key meta.
| Parameter | Type | Description | Default |
|---|---|---|---|
| pagination[myContentType][page] | Integer | Page number | 1 |
| pagination[myContentType][pagesize] | Integer | Page size | 25 |
| pagination[myContentType][withcount] | Boolean | Adds the total numbers of entries and the number of pages to the response | True |
Request:
await fetch(`${API_URL}/api/fuzzy-search/search?query=deresh&pagination[authors][pageSize]=2&pagination[authors][page]=3`);
// GET /api/fuzzy-search/search?query=deresh&pagination[authors][pageSize]=2&pagination[authors][page]=3Response:

}The REST-endpoint accepts an optional parameter to select only some content types the fuzzy search should run for.
| Parameter | Type | Description |
|---|---|---|
| filters[contentTypes] | string | Comma seperated list of the content types to run the search for |
Request:
await fetch(`${API_URL}/api/fuzzy-search/search?query=deresh&filters[contentTypes]=books,authors`);

}While Fuse.js proofs to be an amazing library, it can yield unexpected results and what is to be perceived as "false positives" (by a human) when searching through longer strings. Fuzzysort aims to solve this problem by introducing the evaluation and scoring of exact matches. Since we had issues with Fuse.js and it's underlying algorithm, we opted for fuzzysearch to do the heavy lifting instead.
