Vezi ca balaur e si in categoria spam
Dincolo de glume, sa diferentiem putin. Un motor de cautare nu este un agregator, si nici invers. Diferentele sunt mari. Un agregator, mai ales daca e CMS driven (adica instalat intr-un CMS cu functii interne de cautare - Joomla/Drupal etc), nu este un motor de cautare. Cautarea nu se face in timp real, ci pe un subset de pagini deja existente si publicate in cadrul websiteului respectiv. Cel mai finut exemplu este Yahoo Pipes, care este un mic sistem de meshupuri pe RSSuri, oferind si optiuni de cautare. Asta nu inseamna ca este un motor de cautare.
Motor de cautare = An application that searches for, and retrieves, data based on some criteria, especially one that searches the Internet for documents containing specified words. A search engine caches a web page at regular interval of time, and displays any eventual changes to the user.
Avantaje: continut fresh, algoritmi de relevanta, marime index.
Dezavantaje: stabilitate, costuri
Agregator = A website or software program that gathers (aggregates) and displays web content such as news headlines, blogs, and podcasts from multiple websites to a single location. It allows searches by keyword and provides summaries for browsing (balaur.ro, ziare.com etc).
Avantaje: caching pe rezultate (deci poti face usor spam)
Dezavantaje: continut deseori duplicat/expirat, pentru ca sistemul nu cauta updateuri
