【问题描述】：

我使用以下方法在 PC 上创建了一个 fts4 表：

CREATE VIRTUAL TABLE main USING fts4(word, definition, notindexed=definition);

在 SQLite Studio 中，我查询了一条运行正常的语句：

SELECT rowid AS _id, word, definition FROM main WHERE word MATCH 'はな*';

当我提取数据库以在我的 android 应用程序中使用时，相同的查询给出以下错误：

我在here 中读到了notindexed

感谢您的帮助！

【参考方案1】：

在SQLite 3.8.0 中添加了FTS notindexed 选项，而不是version of SQLite used in most Androids。
