List of fields to aggregate on. Common fields are path for the text type and group or topics for the sheet type

Must be the same length as filters. Each entry specifies the field to apply the corresponding filter in filters. For queries of type text this has no effect since there's only one field to filter text queries on (path. this field is explained in filters). For sheet queries, the following fields can appear in filter_fields: collections (corresponds to the collections that the sheet is in), topics_en (corresponds to the topics for this sheet, translated into English), topics_he (corresponds to the topics for this sheet, translated into Hebrew).

A list of filters to filter results. These filters cannot include RegEx. Any RegEx characters will be escaped. Each filter is applied to the corresponding field in the filter_fields list. E.g. if filters is ["Passover", "Torah Talks"] and filter_fields is ["topics_en", "collections"] then the "Passover" filter will be applied to the "topics_en" field and the "Torah Talks" filter will be applied to the "collections" field. For text queries, filters always applies to the path field of documents. This essentially corresponds to the category path of the book in Sefaria's table of contents (there are some differences with regards to commentary paths). For sheet queries, filters can be applied to collections, topics_en or topics_he. These fields are explained in filter_fields param.

List of fields to sort on. If sort_method = 'score' this list should have exactly one item. Common fields to sort on are comp_date (which list results from titles published chronologically), order (which list results based on Sefaria's table of contents structure), pagesheetrank (most relevant results based on the Sheet Rank algorithm), dateCreated (for sheet results returned chronologically), views (for sheet results based on popularity).
