3.2 situs yang melayani search engine ( mesin pencari )

Mesin pencari adalah program komputer yang dirancang untuk melakukan pencarian atas berkas-berkas yang tersimpan dalam layanan www, ftp, publikasi milis, ataupun news group dalam sebuah ataupun sejumlah komputer peladen dalam suatu jaringan. Hasil pencarian umumnya ditampilkan dalam bentuk daftar yang seringkali diurutkan menurut tingkat akurasi ataupun rasio pengunjung atas suatu berkas yang disebut sebagai hits. Informasi yang menjadi target pencarian bisa terdapat dalam berbagai macam jenis berkas seperti halaman situs web, gambar, ataupun jenis-jenis berkas lainnya. Beberapa mesin pencari juga diketahui melakukan pengumpulan informasi atas data yang tersimpan dalam suatu basisdata ataupun direktori web.
Sebagian besar mesin pencari dijalankan oleh perusahaan swasta yang menggunakan algoritma kepemilikan dan basisdata tertutup, di antaranya yang paling populer adalah Google (MSN Search dan Yahoo!). Telah ada beberapa upaya menciptakan mesin pencari dengan sumber terbuka (open source), contohnya adalah Htdig, Nutch, Egothor dan OpenFTS.
Proses Pencarian
Melakukan pencarian dokumen yang dimuat pada suatu situs bisa begitu mudah dan kelihatannya mungkin sulit juga. apalagi mengignat begitu menyebarnya informasi dimana-mana, bahkan University of Calofornia menyebutkan saat ini telah terdapat lebih dari 50 milyar halaman web di internet, meskipun tidak ada ada satupun yang benar-benar tahu jumlah persisnya.
kesulitan yang mungkin terjadi adalah karena WWW tersebut tidak terdata dalam bentuk yang terstandarisasi isinya. tidak sama halnya dengan katalog yang ada di perpustakaan, yang memiliki standarisasi secara mendunia berdasarkan subjek dari judul buku, meskipun jumlahnya juga tidak sedikit.
Dalam pencarian di web, pengguna selalu memperkirakan kata apa yang di kira-kira terdapat pada halaman yang ingin anda temukan. atau kira-kira apa subjek yang dipilih oleh seseorang untuk mengelolah halaman situs yang mereka kelola, topik apa saja kira-kira yang di bahas.
Jika pengguna melakukan apa yang dikenal dengan pencarian pada halaman web, sebenarnya tidaklah melakukan pencarian. tidak mungkin melakukan pencarian di WWW secara langsung.
Pada web benar-benar terdiri dari banyak sekali halaman web yang ingin disimpan dari berbagai server diseluruh dunia. Komputer pengguna tidak langsung melakukan pencarian kepada seluruh komputer tersebut secara langsung.
Apa yang mungkin pengguna lakukan hanyalah melalui komputer untuk mengakses satu atau lebih perantara yang disebut dengan alat bantu pencarian yang ada saat ini. Melakukan pencarian pada alat bantu itu tadi ke database yang dimiliki. data base tersebut mengkoleksi situs-situs yang ditemukan dan simpan.
alat bantu pencarian ini menyediakan hasil pencarian dalam bentuk hypertext link dengan URL menuju halaman lainnya. ketika anda klik link ini, dan menuju ke alamat tersebut maka dokumen, gambar, suara dan banyak lagi bentuk lainnya yang ada pada server tersebut disediakan, sesuai dengan informasi yang terdapat di dalamnya. layanan ini bisa menjangkau ke manapun di seluruh dunia.
Tidak mungkin seseorang untuk melakukan pencarian ke seluruh komputer yang terhubung internet ini, atau bahkan alat bantu pencarian yang mengklaim bahwa melakukannya, tidak benar.

Saat ini, tiga bentuk dari alat bantu pencarian ini. Menggunakan strategi yang berbeda untuk memanfaatkan kemampuan potensial dari masing-masing nya, yaitu
