[Xapian-discuss] Indexing text files with Xapian

[Justine Demeyer]

Thanks for your answer!!

You said : " once you've read a file, you can pass its contents to Xapian to
index and then later search the database to find matching files."

How do I pass the content of a file to Xapian? Word by word?

Thank you.
