Regarding Text Analysis in SAP HANA

HI

I was following some blogs on how to index the documents for text analysis and tried in my test system.

I have some pdf files which I stored in blob field. I used python scripts to transfer the conent to HANA DB .

I could see the content in the table when I run a SELECT QUERY.. since it is an unstructured data , I ran this query

for the text analysis

Create FullText Index"PDF_FTI"On"PRESS_RELEASES"("File_Content")

TEXT ANALYSIS ON

CONFIGURATION 'EXTRACTION_CORE';

This created a table $TA but the index table is blank.

Can you share your thoughts on where it might have gone wrong ?

I use the SYSTEM user and it is an PDF file in English.

Regards
