It would help if you allowed a toggle in the search settings for each index, to allow for facet hits with search hits. |

Hey @smultar 👋 What do you mean by that? I'm not sure to understand! Thanks! |

Normally when I query Meilisearch. It brings back a variety of hits based on the search criteria. We should add an option, that allows hits for possible facets, based on the results. So we would be getting a set of |

Does it relates to "It will also allow injecting global search parameters to allow to find facets that match according to the current search context (e.g., query terms, filters, etc..)"? |

Hello everyone 👋, 🔔 EDIT: A new prototype version is accessible here 🔔 Here is the current prototype you can use to test the new Search for Facet Values feature: You can use the feature this way or look at the original PR for more info: # send some documents in your database
cat movies.json | xh 'localhost:7700/indexes/movies/documents' 'content-type:application/json'
# Make your facet filterable
echo '{ "filterableAttributes": ["genres"] }' | xh PATCH 'localhost:7700/indexes/movies/settings'
# Do your query to search for facets
echo '{"q": "spiderman", "filter": "price > 10", "facetName": "genres", "facetQuery": "act" }' | xh 'localhost:7700/indexes/movies/facet-search'

Hello everyone 👋, 🔔 EDIT: A new prototype version is accessible here 🔔 Yes! The second prototype is already here! You can test the new Search for Facet Values feature: You can use the feature this way or look at the original PR for more info: # send some documents in your database
cat movies.json | xh 'localhost:7700/indexes/movies/documents' 'content-type:application/json'

echo '{ "filterableAttributes": ["genres"] }' | xh PATCH 'localhost:7700/indexes/movies/settings'
# Do your query to search for facets
echo '{"q": "spiderman", "filter": "price > 10", "facetName": "genres", "facetQuery": "act" }' | xh 'localhost:7700/indexes/movies/facet-search'In this new version we fixed a lot of issues regarding error codes and the output JSON object.

Hi, I have this running locally... I was hoping it would be compatible with instantsearch refinementlist searchable attribute? https://www.algolia.com/doc/api-reference/widgets/refinement-list/angular/ Is this not the case? I currently get this I see we would need an updated instant meilisearch library? - is that within scope of this work? searchForFacetValues: async function (_: any) {
return await new Promise((resolve, reject) => {
reject(
new Error('SearchForFacetValues is not compatible with Meilisearch')
)
resolve([]) // added here to avoid compilation error
})
}, |

Hey @nacoleman It will work on instant-meilisearch! Normally the refinement list One small caveat is that you won't be able to sort it by count. Which should not be an issue if you don't have more than 100 facet values per facet. |

Hello everyone 👋, 🔔 EDIT: A new prototype version is accessible here 🔔 Yes! The third prototype is already here! You can test the new Search for Facet Values feature: You can use the feature this way or look at the original PR for more info: # send some documents in your database

Is the facetName only allowed to have one? What happen if I want to query "genres" and "age"? |

Hello @mech 👋 Is there a particular reason to query two facets both at the same time in one query? I'm happy to learn more! We build that API with the most typical facet search UI in mind, where an end-user will search one facet at a time to refine his navigation. |

Hello everyone 👋 We released a new prototype for the search for facet values. Introduced changes
How to run the prototype?You need to start from a fresh new database (remove the previous used data.ms) and use the following Docker image: docker run -it --rm -p 7700:7700 -v $(pwd)/meili_data:/meili_data getmeili/meilisearch:prototype-search-for-facet-values-6How to use the prototype?# send some documents in your database
cat movies.json | xh 'localhost:7700/indexes/movies/documents' 'content-type:application/json'
# Make your facet filterable
echo '{ "filterableAttributes": ["genres"] }' | xh PATCH 'localhost:7700/indexes/movies/settings'
# Do your query to search for facets
echo '{"q": "spiderman", "filter": "price > 10", "facetName": "genres", "facetQuery": "act" }' | xh 'localhost:7700/indexes/movies/facet-search'

Hello Meilisearch team and @macraig , I hope this message finds you well. I've been exploring the recent additions to Meilisearch, particularly the facet search feature. First and foremost, I want to express my appreciation for the ongoing development and improvement of your excellent open-source search engine. I'm currently working on a project where we need to adapt the facet search feature to provide more comprehensive results to our users. Meilisearch currently implemented it so that facet searches are only matched from the start of a given string and are not highlighted. That means when a user searches "Bus" the facet option "Green Bus" will not be matched and displayed (if I understand correctly). Before I dive into the code and start making modifications, I wanted to check if there's already any work done in this direction within the Meilisearch codebase. If there is, I'd greatly appreciate it if you could point me in the right direction or provide some guidance on which parts of the code I should investigate to achieve these enhancements. I look forward to your response and potentially collaborating with the Meilisearch community to make these improvements. |

Hey @amonin7 👋 Thank you very much for this feedback. The following feature you describe was something we wanted to implement in the future.
However, when we fixed a bug in the facet search (before we released it), we changed the way we store the "words" extracted from the facet fields, and this enables more flexibility. Implementing facet word-based search is "straightforward" now.
We we not prioritize this change on our side and we will work on other features. However, I would be happy to help you make the change on the Meilisearch codebase. I'll describe a little further the way I would do it and will continue to help you with the PR you open 🥹

Currently, there is no way to natively search for a facet value among a distributed facet, which can be significant depending on the dataset. Some facets can hold hundreds or thousands of values.
Introducing a search for facet values feature would allow end-users to discover and search for specific facet values that match their needs and thus speed up their finding.
We want to enable you to quickly implement that type of faceted search experience in a few lines of code.
We have planned to work on the first iteration for v1.2, and a prototype should be available in the next few weeks.
This prototype should provide the ability to search in facets using prefix search while being typo tolerant.
It will also allow injecting global search parameters to allow to find facets that match according to the current search context (e.g., query terms, filters, etc..)
Fields defined as
filterableAttributeswill be facet searchable without further configuration on the engine side.Our research has permitted us to discover some grey areas for which we would like to evaluate the degree of importance to define better if this first iteration is sufficient and to prepare successive iterations on this feature.
We have listed the questions we would like your feedback on to assess your needs better.
filterableAttributesdistributed as facets impossible to be searched on as facet?Do you see anything we may miss?
Thank you for your feedback!
