My
future application had two mains challenges:
- The first one is, how to connect to Yahoo mail and download
automatically more than 210 e-mails
each week.
- The second challenge is, how to create an indexing,
storage and search engine
to retrieve quickly this information.
After several months of development a beta release of
ASE (Advanced Search Engine) was born.
Day after day I improve ASE functionalities and fixed
some bugs.
At the glance, the capabilities of ASE are the following:
- 2 Giga byte for the storage of
the key word, that’s means around 618,000
key word
- 2 Giga byte for the storage of the
files names, that’s means around
41,600 files.
Why this limitation at 2 GB ? Fore short, in the world
of computing a microprocessor manipulate more quickly
a king of data. Called byte, word or long word respectively
2p8,2p16, 2p32 bites. In the structure of my database
there is a table that’s store the offset* of each
key word and the offset their files names, those data
are store in long word (2p32 ). Due to this limitation,
the offset of the file name I can store limit my maximum
size store at around 2 Giga byte.
Today (11/06/06) I store 267,444 key
word and 18,035 files in my Yahoo Group
database. Offset
is a relative position from a specific position. For instance
if you have a starting position at 7A0h and on offset
of 01Ch your news value is 7BCh.
