Hi Everyone, i hope anyone would help me, This is about on our ongoing thesis

In ORACLE 12c they discussed in their Site that 12c now supports unstructured data management. So this is my question:

IS IT POSSIBLE FOR THE ORACLE 12c DB to text-mine(TEXT MINING) the contents of a PDF,MICROSOFT WORD,EXCEL,PPT and WORD? and DISPLAY THE FILES on the GUI specifically on the VB.NET (LISTBOX)?

The flow of our system is that if the user will query a keyword, such as if the user would input a keyword (for example: JOHN), all the files(PDF,MICROSOFT WORD,EXCEL,PPT and WORD) which was saved directly to the ORACLE DB which contains the keyword JOHN will be displayed on the VB.NET(listbox).

IS IT POSSIBLE?? PLS HELP ME.. THIS IS FOR OUR THESIS. PLS HELP :(
