    selectedMatch$: Observable<string>,
    getMatches: (text: string) => Observable<string[]>,
    opts: InputDriverOptions) {

    const typedWord$ = keyUp$
      .debounceTime(opts.debounceMs)
      .filter(event => isTyping(event.keyCode))
      .map(event => {
        const { value: fullText, selectionStart } = (event.target as HTMLInputElement);

        const wordResults: TextRun[] = findCurrentWord(fullText, selectionStart);

        return wordResults;
      })
      .share();

    const longEnoughWord$ = typedWord$
      .filter(wordResults => wordResults.length > 0)
      .map(wordResults => wordResults[0])
      .filter(wordResult => wordResult.text.length >= opts.minWordLength);

    const emptyMatches = [];

    const notSuitableWord$ = typedWord$
      .filter(wordResults => wordResults.length === 0
        || wordResults[0].text.length < opts.minWordLength)
      .map(_ => emptyMatches);

    const matchingCompletions$ = longEnoughWord$
      .switchMap(wordResult => {
        const matches$ = getMatches(wordResult.text)
          .catch(_ => Observable.of([] as string[]));

        return matches$;
