我有 2 个FTS表：search和search_eng。我正在尝试从search_eng获取匹配词的entry_id。然后我根据这些entry_id从搜索中获取值。但是当我尝试以下面显示的方式实现它时，它给出了错误：SQL logic error。这是因为MATCH ing 超过 2 个值？如果不是我做错了什么？

//takes entry_id, g_value where matches word 
        query = "SELECT * FROM search_eng WHERE g_value MATCH '"
                + lookingFor + "' LIMIT 10";
        cursor = db.rawQuery(query, null);
        if (cursor.moveToFirst()) {
            //if cursor is not empty
            int num = 0;//counter for loop
            query = querySelectFromTableWhere;//"SELECT entry_id AS _id, re_value, ke_value, g_value, pos FROM search WHERE "
            do {
                if (num == 0) {
                    //for the first time
                    //query for getting all data of words which matches with entry_id which was got from search_eng
                    query = query
                            + " entry_id MATCH '"
                            + cursor.getString(cursor
                                    .getColumnIndex("entry_id"))+"'";
                } else {
                    //next tries: 2nd time, 3rd time...
                    //query for getting all data of words which matches with entry_id which was got from search_eng
                    query = query
                            + " OR entry_id MATCH '"
                            + cursor.getString(cursor
                                    .getColumnIndex("entry_id"))+"'";
                }
                num++;//plus counter
            } while (cursor.moveToNext());
            query=query+" LIMIT 10";
        }

请参阅此处sqlite的文档。

要匹配多个单词，您必须OR在单词之间添加，而不是MATCHes。就像是：

SELECT entry_id AS _id, re_value, ke_value, g_value, pos
FROM search
WHERE entry_id MATCH 'firstWord OR secondWord`

是的，OR 在里面''。
