How to search newly created data through content search without rebuild index?

Hi All,


Could you let me know how we can rebuild particular template id index without rebuilding Sitecore_master_index through programming as i am facing this issue , i am adding data in Sitecore content tree through programming and find that data through content search API though code. However , newly created data is not searching. When i rebuild index then it is showing in result. I am adding data continuously so every time i can not rebuild index it will time consuming. Can someone assist me how i can achieve this functionality or guide me for the approach which i am using ?
