 The last `FullTextOption` parameter clarifies the given FTS request. If you omit the `FullTextOption` parameter,
 then the default value will be set for each possible option. Currently, we only have one option named `mode`.
 And as we extend the FTS feature, more options will be added. Please note that the format of `FullTextOption`
 is a record, thus you need to put the option(s) in a record `{}`.
 The `mode` option indicates whether the given FTS query is a conjunctive (AND) or disjunctive (OR) search request.

 generating grams as in an ngram index, we generate tokens (e.g., words) and for each token, construct an inverted list that includes the ids of the
