sorry, i think u misunderstand my question.
let's me explain once again. my database consists of 4 fields,
1. pageID
2. pagename
3. content
then, i will let user to search a keyword inside the field 'content'.
keyword=introduction
then, i will display this to them:
result found:
1.'$pagename'
Description: partial content of '$keyword'
(ie. Description:...adjd ajsdj afj '$keyword' .......)
