Kukho imigaqo embalwa engundoqo ongayisebenzisa ngokubanzi phantse zonke iinjongo zokukhangela ngaphandle ukuba ufumane oko kukufunayo, kwaye esinye sezixhobo ezisisiseko zisetyenziselwa ukongeza kwaye ususe iimpawu kwi-web search query . Oku kwaziwa ngokuba yi-Boolean ukukhangela kwaye yenye yeendlela zokuqala ezisetyenziswayo kwimigudu yakho yokukhangela (kunye nenye yeyona mpu melelo). Ezi zakhono zilula, kodwa zisebenza ngokugqithiseleyo, kwaye zivame ukusebenza kuwo onke ama- injini yokukhangela kunye neenkcukacha zogcino kwiWebhu.
Yintoni i-Boolean Search?
Ukukhangela kwe-Boolean kukuvumela ukuba udibanise amagama kunye namazwi usebenzisa amagama NO, OKANYE, AKUNYE NAKUYA (mhlawumbi uyaziwa ngokuba ngabaqhubi be-Boolean) ukukhawulela, ukwandisa, okanye uchaze ukukhangela kwakho. Injini ezininzi zophando ze-intanethi kunye nee-directories zeWebhu zizenzekelayo ezi zikhethi ze-Boolean zokuphenya, kodwa umseshi olungileyo weWebhu kufuneka aqonde indlela yokusebenzisa abasebenzisi bokuqala beBoolean.
Igama elithi Boolean livela phi?
UGeorge Boole, isazi seMathematika kwisiNgesi ekhulwini le-19, wavelisa "i-Boolean Logic" ukuze adibanise iingcinga ezithile kwaye akafaki iikhontrakthi ezithile xa efuna iinkcukacha zolwazi.
Ininzi yolwazi lwe-intanethi kunye neenjini zophando zixhasa ukuseshwa kweBoolean. Amasu okukhangela aseBoolean angasetyenziselwa ukwenza uphando olufanelekileyo, ukusika amanqaku amaninzi angahambelani.
Ngaba i-Boolean Search Complicated?
Ukusebenzisa i-Boolean Logic ukuze uwandise kunye / okanye unciphise ukukhangela kwakho akuyinkimbinkimbi njengoko kuzwakala; Enyanisweni, usenokwenza oko. I-logic ye-Boolean iyigama elisetyenziswe ekuchazeni imisebenzi ethile enengqiqo esetyenziselwa ukudibanisa imigangatho yophando kwiinkcukacha ezininzi zeenjini zolwazi kunye neenkcukacha kwi-Net. Akuyiyo inzululwazi yesayensi, kodwa ngokuqinisekileyo ivakalisa izandi (zama ukuphonsa eli binzana kwingxoxo eqhelekileyo!).
Ndiyenza njani i-Boolean Search?
Unokukhetha ezimbini: ungasebenzisa abaqhubi be-Boolean abaqhelekileyo (NYE, OKANYE, AWAKHONA, okanye NGAPHAMBILI, okanye ungasebenzisa izibalo zabo ezilinganayo.Kuxhomekeke kuwe, umseshi, ngoluphi indlela okhululekile ngayo. : I
AbaSebenzi Bosesho boBoolean
- Umsebenzisi we-Boolean uphendlo kwaye ulingana nesimboli "+".
- Umqhubi we-Boolean u- AKHONA ulingana ne "-".
- Umsebenzisi we-Boolean okhangelayo OKANYE isilungiselelo esingagqibekanga salo naliphi na injini yokusesha; intsingiselo, zonke iinjongo zokukhangela ziya kubuya onke amagama othayipha kuyo, ngokuzenzekelayo.
- Umqhubi we-Boolean u- NEAR ulingana nokubeka umbuzo wokukhangela kwiingcaphuno, oko kukuthi, "i-sponge bob squarepants". Ubaluleke kakhulu ukuxelela injini yokukhangela ukuba ufuna onke la magama, kulo myalelo othile okanye eli binzana elithile.
I-Basic Math - i-Boolean-Inokukunceda kwi-Web Search Yakho
Izibalo ezisisiseko zinokukunceda ngokwenene kwi-Web search quest yakho. Nantsi indlela esebenza ngayo:
- Isimboli esingenanto:
Sebenzisa "-" uphawu xa ufuna i-injini yokukhangela ukufumana iphepha elinelinye igama lokusesha kubo, kodwa ufuna i-injini yokukhangela ukuba ungabandakanyi amanye amagama ahambelana naloo gama losesho. Umzekelo:
- Superman -Krypton
Uxelela iinjini zokukhangela onokuthanda ukufumana amaphepha anamazwi athi "Superman", kodwa ungafaki uluhlu olubandakanya ulwazi malunga ne "Krypton". Le yindlela elula kwaye elula yokukhupha ulwazi olongezelelweyo kwaye unciphise uphando lwakho; kunye kunye unokwenza umtya wegama elingabandakanywa, njengolu: superman -krypton - "lex luthor".
- Isalathisi sokudibanisa:
Ngoku ukuba uyazi indlela yokuphelisa imigaqo yokukhangela, nantsi indlela ongayongeza kuyo, usebenzisa uphawu "+". Ngokomzekelo, ukuba unemiqathango ekufuneka ibuyiselwe kuzo zonke iziphumo zakho zophando, unokubeka isimboli esicwangcisiweyo phambi kwemigangatho oyifunayo ukuba ifakiwe, njengale:
- ibhola + nfl
Iziphumo zakho zokukhangela ziza kuba zibandakanya le mibandela.
Ngakumbi malunga neBoolean
Gcina ukhumbule ukuba akuzona zonke iinjinjini kunye neenkcukacha ezixhasa imigaqo yeBoolean. Nangona kunjalo, abaninzi banako, kwaye unokufumana lula ukuba lowo ufuna ukuyisebenzisa usekela le nkqubo ngokubonisana ne-FAQ's (Imibuzo Ebuzwa Ngokuphindaphindiweyo) kwi-injini yokukhangela okanye kwikhasi lekhaya lekhowudi.
Ukubhengezwa: BOO-le-un
Kwaziwa nangokuthi: i- Boolean, i-boolean logic, i-boolean search, i-boolean operators, i-operole boolean, inkcazelo ye- boolean , i- boolean search , i-boolean imiyalelo
Imizekelo: Ukusebenzisa nokunciphisa uphando ngokudibanisa amagama; liya kufumana amaxwebhu asebenzisa zombini amagama ophando oyicacisayo, njengale mzekelo:
- EPortland naseOregon
Usebenzisa OK okanye ukwandisa uphando ukufaka iziphumo eziqulethwe ngamagama owafake kuwo.
- Inkululeko okanye i-democrat
Ukusebenzisa i-NOT kuyakunciphisa uphando ngokungabandakanyi amagama athile ophando.
- Oregon AWUkho uhambo
I-Boolean Search: Usetyenzisayo Ukukhangela ngokufanelekileyo
Ubuchwephesha bokukhangela boolean ngenye yeengcamango zesiseko phantsi kweenjini zokusesha zanamhlanje. Ngaphandle kokuba siqaphele, sisebenzisa ngokunjalo inkqubo yokukhangela elula phantse xa sicwangcisa umbuzo wokukhangela. Ukuqonda inkqubo kunye nolwazi lwe-Boolean ukusesha kuya kusinika ubuchule obuyimfuneko esisenza ukuba uphando lwethu luphumelele ngakumbi.
