searchableAttributes property
Attributes used for searching. Attribute names are case-sensitive.  By default, all attributes are searchable and the Attribute ranking criterion is turned off. With a non-empty list, Algolia only returns results with matches in the selected attributes. In addition, the Attribute ranking criterion is turned on: matches in attributes that are higher in the list of searchableAttributes rank first. To make matches in two attributes rank equally, include them in a comma-separated string, such as \"title,alternate_title\". Attributes with the same priority are always unordered.  For more information, see Searchable attributes.  Modifier  - unordered(\"ATTRIBUTE\").   Ignore the position of a match within the attribute.  Without a modifier, matches at the beginning of an attribute rank higher than matches at the end.
Implementation
