Questa e' paurosa
Yet another query-based factor may relate to the extent to which a document appears in results for different queries. In other words, the entropy of queries for one or more documents may be monitored and used as a basis for scoring. For example, if a particular document appears as a hit for a discordant set of queries, this may (though not necessarily) be considered a signal that the document is
spam, in which case
search engine 125 may score the document relatively lower.
In pratica dice che un sito che compare per piu' key discordanti puo' (non necessariamente pero') essere considerato come un segnale che il documento e' spam, in questo caso gli verra' assegnato un punteggio relativamente basso
