Search Engine Project

Last week I started my last project before my thesis. It's about implementing a search engine and consider the complexity of searching algorithms. So far, what I have realized is that it is more about choosing the right data structure to store your data, than optimizing the search algorithm.. At least up to now, the only thing I was doing to optimize the search was to change the data structures.. This week I will focus on the search algorithm and some extra features..

My personal motivation is to make the search faster than the one's implemented by other students. I have a friend that did this project a year ago and I have some measurements from some other students that did it 2 years ago.. Let's see.. I have 3 more weeks..

Είμαι σίγουρος ότι στο DATA σου έμαθαν την σειριακή αναζήτηση!!!

I have a friend in the search engine bussiness. You may know him, his name is Yiannis Tsoukalidis. He may be able to help you...

αααχχχ.. ωραίες εποχές οι εποχές του Data..

Yiannis what? Tsoukalidis? Is he Greek? I know only Sakis, Koula, Dimitris and Eva.. There are more? :)

Yes, I think there is one more.. not Yiannis... but Ioannis and he is working in MSN Search Engine..!!

Stavros said...

thanks Loukoumaki!! Ελπίζω να μην κολήσω, αλλά ποτέ δεν ξέρεις..

Ioannis, Ioannis.. I don't know him.. (I am laughing while thinking to post a photo of us two from a party, but he will not be very happy if he learns about it :D :D :D )
