我需要帮助来构建一个查询句子中的单词，一旦发现它应该在搜索到的单词之前和之后显示2个单词。
示例1： -
Input Sentence :- "Hi my computer is down at 10 am due to power issue"
search keyword ( which is pre-defined ) :- down
expected output :- "computer is down at 10" ( 2 words before and after of the searched keyword )
示例2： -
Input Sentence :- "Hi my database is down at morning 8am due to memory"
search keyword ( which is pre-defined ) :- down
expected output :- "database is down at morning" ( 2 words before and after of the searched keyword )
对于Query构建，请将表名视为＆＃34;输入＆＃34;和保留句子的列为＆＃34;描述＆＃34;
感谢您的帮助!!
