[Xapian-discuss] Indexing images, .zip, .dwg and other binary files

[Brian Burton]

I have finally cobbled together a solution so I'll post it here for anyone
else who has this question.

1) Open the xapian-omega source directory and edit the omindex.cc file.

2) Starting at line 539 (in version 1.0.21) change these lines:
    } else {
      // Don't know how to index this type.
      cout << "unknown MIME type - skipping" << endl;
      return;
    }

to this:
    } else {
      dump = file;
      title = file;
      keywords = file;
      sample = file;
    }

This creates a sort of "catch all" to index files even if it doesn't know
what they are.

3) Around line 845 where the mime_map array is set up, add your extensions
and their mimetypes like so:

    mime_map["jpg"] = "image/jpeg";
    mime_map["jpeg"] = "image/jpeg";
    mime_map["gif"] = "image/gif";
    mime_map["png"] = "image/png";
    mime_map["bmp"] = "image/bmp";
    mime_map["psd"] = "image/photoshop";
    mime_map["dwg"] = "application/acad";
    mime_map["mp3"] = "audio/mpeg";
    mime_map["avi"] = "video/avi";
    mime_map["mpg"] = "video/mpeg";

4) Then compile xapian-omega as you normally would.

Hope this helps someone else.
