Metasearch Systems: imizekelo, isimiso ukusebenza

I-Internet isekhona isibini eminyaka eyadlulayo, asakhulayo kuphela kumazwe amaninzi aphuhlileyo, mzuzu yangoku ukuphuhlisa isantya stretelnymi, kunye into eyogqitha. Yonke imihla isixa ngolwazi ubukhula ngokucacileyo, emele i data dynamically variable. Ngokuqhelekileyo, nobunzima enjalo lolwazi kufuneka ukulawula ngandlel 'ithile. Nale njongo ngexesha layo kungenwe iinjini zokuphendla. Kodwa okwangoku lokujongana lonke umthamo lolwazi, rhoqo esiza network akakwazi nayiphi na injini yokukhangela. Ingakumbi ukuba uthathe ingqalelo thina umahluko algorithms injini yokukhangela. Emva kokubuza isicelo kwi iinjini zokuphendla ezahlukeneyo, nokuba ilingana olunye iinqwelwana, umsebenzisi akanokukwazi ukufumana iziphumo ezahlukeneyo kakhulu. Ngoko ke kuyimfuneko ukuba ukuphucula inkqubo ekhoyo. Ukusebenzisa ukulinganiswa kwiziphumo, kakhulu phambili kwe-SS ziye yaphunyezwa software, izibonelelo ezongezelelweyo - inkqubo metasearch.

Ntoni metasearch

Kwimeko-bume Internet ekuthiwa umatshini metasearch nabakwaziyo ukwenza isicelo lomsebenzisi kunye neziphumo iinjini kakhulu ethandwa search. Ngamanye amazwi, esibonakalayo akukho eyahlukileyo kuleyo search engine njengesiqhelo. Kodwa xa unikwa isicelo esithile, oko akuthethi asebenzise imithombo kunye nokujikwa isicelo ukuya phambili iinjini zokuphendla, yaye ngenxa yoko umsebenzisi ubona uluhlu lweziphumo evela oovimba emanyeneyo iinjini ezahlukeneyo uphendlo. Kulo mzekelo, ukuze kube lula usebenzisa olu hlobo ukukhangela lususwe zonke iilinki phindo, nto leyo inceda ukuphucula iziphumo kwemveliso data.

buhle

Uncedo ibalulekileyo, nto leyo liyi inkqubo metasearch, kukwenza ukuba ixesha elifutshane ngaphandle umgudu okhethekileyo ukufumana iziphumo iinjini ezahlukeneyo uphendlo ngaphandle phindo kwale ngxelo. Ukusebenzisa inkqubo enye kuphela ngenxa structuring ulwazi, uyakwazi ukufumana uluhlu olubanzi lweziphumo ezivela kwimithombo eyahlukeneyo ngaphandle kwesidingo sokusebenzisa udweliso oluninzi top.

Abasebenzisi abaninzi badla ngokujongana ingxaki enjalo ukuba ezinye iinkcukacha ezinqabileyo, amaxwebhu okanye iinkqubo kunokubonwa kwenye injini yokukhangela kunye ndingekhoyo ngokupheleleyo kwabanye. Ngenxa yoko, ukuba umntu uqalisa ukusebenzisa ezo yena, enyanisweni, bafumana ulwazi esinqabileyo. Kunye nazo kanye kwakhona ingxaki efanayo. Kuyinto enye isicelo injini yokukhangela okhethiweyo akanalo ungakufumani, kodwa uboniswa kwi endala, abangakhange kwizinto ezilindelweyo. Yiyo le ukushiyeka idini isisombululo kwinkqubo metasearch ubomi yokwenene, abasebenzisi ezona ziphumo elungeleleneyo.

ukushiyeka

Zonke ukushiyeka metasearch isuka zalo eziluncedo, njengokuba ukuqhubekeka yabo ubhalo. In yayo metasearch index database kungekhona nje ezinjalo, ngoko ke URL kwaye dibanisa iziza zabo akunakwenzeka. Enye, Ububi kunokuba ebalulekileyo uluhlu kakhulu owayenomgutyana iimpawu syntactic, ukuba kunzima kakhulu ukwenza i iinkcukacha retrieval phambili.

Ubukhulu becala kusetyenziswa kwiinkqubo amabini ezahlukeneyo data retrieval kunye, ngokwendalo, advanced iinketho zabo uphendlo abahlukene. Kakade ke, ngalo mzuzwana sele kukho inkqubo metasearch, ephuhliswe ngokusekelwe kwisikolo esitsha. Ukuba bathathe ingqalelo zonke umehluko phakathi PS kunye, ke ngoko, bekhangela iimpawu eliphezulu kakhulu. Kodwa lo gama iinkqubo ezinjalo ezincinane, ngoko umba ayikaphenduleki.

uhlobo

Ngaphambi siqhubeka ukuqwalasela usebenziso ezi nkqubo, kubalulekile ukukhumbula ukuba kukho umahluko uphendlo loluhlobo. Uhlobo classic kuxoxwe ngasentla kwaye isekelwe kwinto yokuba i-SS ephatha ngayo ekwandiseni ezinye iinjini zokuphendla, uze emva koko edlulisela ulwazi kumsebenzisi, loo nto ithathwa eqhelekileyo kakhulu kwaye ethandwa. Kodwa kuthathelwa ingqalelo ukuphuculwa kunye neenguqu kwezi zibonelelo kukwakho nezinye iintlobo kweenkqubo meta-uphendlo.

Enye kakhulu zithandwa ekhoyo okwangoku ityala apho ulwazi kwiziphumo yombuzo egxile ikwisakhelo, zonke iinkcukacha zibe ngaphakathi metastranitsy mnye. Kufuneka kuqatshelwe ukuba zonke isakhelo kulo mzekelo iqulethe iphepha-enjini yokukhangela lokuqala eyakhethwayo target. Kwezinye iimeko, inikeza isibini lamaphepha, kuxhomekeka kwinani umsebenzisi PS.

Kwakhona ethandwayo ukhetho "Bonke ukufuna enye." Oko kukuthi, umsebenzisi ukuvula ifom search, esebenzisa leyo angenza isicelo i esingenakubalwa of iinjini ezahlukeneyo uphendlo. Kodwa ngokwenza isicelo, oko magunyaangazithumela kuphela lowo ekhethiweyo. Ngamanye amazwi, uphendlo - injini yokukhangela. Nto ke ayithethi elula nje, umzekelo, kwi version zakudala.

I-injini zixhaphakileyo meta-uphendlo

Phakathi iinkqubo ezinjalo eqongeni edume Classic yaba inkqubo metasearch Vivisimo. Yafumana ukuba iindwendwe million elinambini unique ngenyanga nganye. Kodwa kubalulekile ukuphawula ukuba i-ukuthandwa akuthethi isiqinisekiso oluzenzekelayo umgangatho kunye nentuthuzelo yokusetyenziswa yobutyebi.

isikolo esidala

Okwangoku, zininzi metapoiskovikov zoqobo. Bonke bephela banembali ende kwendalo, ukuhambela kunye nokuphila. Ukuziqhelisa, nganye kwezi nkqubo unalo efanayo umgaqo, ke ngoko, ukuba abaphathe ngokwahlukileyo akukho luncedo.
