Why does Google (and others...) show only 1000 results?
Anyone can answer this question to me? Technically, I have noticed in a practical experiment at ::buscas.com there is a "deep process" to seek a keyword an entire text field in complex databases structures (over 5 million records, for example).
I t means, when the keyword is in the begging of the indexed field (i.e. LINK at LINKING), it is easy and quick to find it, but when this same keyword is a partial string in a big word (i.e. LINK at FIRSTLINKMEDIA), as a combined one (or mixed string), it takes time to be found.
Because of that [and other "unknown" purposes], the majority of very popular search engine systems [Live Search, Yahoo, Dogpile besides Google], limit the user searches to some thousand results, even if you check a database that brings some million valid records. Maybe the users don´t want to wait more than some milliseconds... too much time (???).
By the way, if I receive 52,700,000 results to the keyword "Brazil" (my country name in English), but I "only" can see the resume of "first" 1000 links (99 pages), why the other 52,699,000 need to exist?
It is really true to say: there is a lot of information stored at databases [i.e. machine side], but humans are responsible to create "filters" or "indexes" to decide which records will be "visible".
Would it be Page Rank side?
Thanks Larry and Sergey.
