Unfortunately, there is no built-in tokenizer that processes stop words, so you will either need to implement your own tokenizer in C, or filter the stop words from the list manually, insert the pre-selected text / pre-filtered text in the corresponding column of the FTS table, or use a somewhat confusing the scheme in which you insert the text into the FTS column, retrieve it back after it is tokenized, filter it and then update the value of the column.
