You can use itextsharp or LEADTOOLS programming SDKs to accomplish this. For itextsharp, I found the following threads that discuss similar requirements to yours:

For LEADTOOLS, the Document Viewer HTML5/JavaScript from LEADTOOLS provide the ability to search for a specific text, find and highlight it in a PDF file. You can try the online application using this link (select the menu "Edit\Find text" to search for text):
