it’s difficult to give an exact answer without more context - would you like to only search within the brand attribute?
If so, you can configure which attributes can be searched in the “Searchable Attributes” section, under the “Ranking” tab in your index.
Here you can tell Algolia which attributes you would like to be made searchable, and in which order you consider each to be important. For example, if you list “brand” before “name”, records that have matches in the brand attribute will be considered more relevant than those in the bane attribute.
