Kunemigomo embalwa eyisisekelo ongayisebenzisa ngokuphumelelayo cishe kuzo zonke izinjini zokusesha ngaphandle ukuze uthole ukuthi yikuphi okufunayo, futhi enye yamasu ayisisekelo isebenzisa ukungeza futhi isuse izimpawu kumbuzo wakho wokusesha iwebhu . Lokhu kuvame ukubizwa ngokuthi yi-Boolean search futhi ingenye yezindlela ezisemqoka kakhulu ongazisebenzisa emikhankasweni yakho yokusesha (kanye nenye yepumelelo kakhulu). Lezi zindlela zilula, kodwa zisebenza ngendlela ephawulekayo, futhi zivame ukusebenza cishe kuwo wonke ama- search kanye nezincwadi zokusesha kwi-Web.
Iyini i-Boolean Search?
Ukuseshwa kwe-Boolean kukuvumela ukuba uhlanganise amagama nemishwana usebenzisa amagama NOMA, Awu, HHALA futhi uFUNYE (okunye okubizwa ngokuthi ama-boolean opharetha) ukukhawulela, ukwandisa, noma uchaze usesho lwakho. Iningi lezinjini zokusesha ze-inthanethi nama-Web directories ahluke kulezi zimingcele zokusesha ze-Boolean noma kunjalo, kodwa usesho oluhle lwe-Web kufanele azi ukuthi angasebenzisa kanjani abasebenzisi bokuqala be-Boolean.
Igama elithi Boolean livelaphi?
UGeorge Boole, isazi sezibalo saseNgisi ekhulwini le-19, wahlakulela "i-Boolean Logic" ukuze ahlanganise imiqondo ethile futhi akhiphe imibono ethile lapho ecwaninga imininingwane yolwazi.
Ulwazi oluningi lwe-intanethi nezinjini zokusekela zisekela ukusesha kwe-Boolean. Amasu okucinga we-boolean angasetshenziswa ukwenza usesho oluphumelelayo, ukukhipha imibhalo eminingi engahlobene.
Ingabe ukusesha kwe-Boolean kuyinkimbinkimbi?
Ukusebenzisa i-Boolean Logic ukukhulisa futhi / noma unciphise ukusesha kwakho akuyona okunzima njengokuzwakalayo; empeleni, kungenzeka ukuthi usuvele wenza. I-logic ye-boolean yiyona nje igama elisetshenziselwa ukuchaza imisebenzi ethile enengqondo esetshenziselwa ukuhlanganisa amagama okucinga kumininingo eminingi yolwazi yokusesha kanye nezinkomba kwi-Net. Akuyona isayensi ye-rocket, kodwa ngokuqinisekile izwakala fancy (zama ukuphonsa le nkulumo engxoxweni evamile!).
Ngenza kanjani usesho lwe-Boolean?
Unezinketho ezimbili: ungasebenzisa ama-opharetha ajwayelekile ase-Boolean (NOMA, Awu, AKHONA, noma AWAKHONA, noma ungasebenzisa izibalo zawo ezilinganiselwe. Kuncike kuwe, oseshayo, ukuthi iyiphi indlela okhululekile ngayo. :
Ama-Operator Search Boolean
- I-Boolean search operator futhi ilingana nesibalo "+".
- Umsebenzisi we-Boolean search CHA akalingani ne "-" uphawu.
- Umsebenzisi we-Boolean search OR noma ukulungiswa okuzenzakalelayo kunoma iyiphi injini yokusesha; okusho ukuthi, zonke izinjini zokusesha zizobuyela kuwo wonke amagama othayipha kuwo, ngokuzenzakalelayo.
- Umqhubi we-Boolean wokusesha u- NEAR ulingana nokubeka umbuzo wosesho kumaphuzu, okungukuthi, "i-sponge bob squarepants". Usuke utshele injini yokusesha ukuthi ufuna wonke lawa magama, kulolu hlobo oluthile noma le nkulumo ethize.
Izibalo eziyisisekelo - i-Boolean - Ingasiza Ngesidingo Sewebhu Sakho
Izibalo eziyisisekelo zingakusiza ngempela ekufuneni kwakho kwewebhu. Nakhu ukuthi kusebenza kanjani:
- Uphawu lokunciphisa:
Sebenzisa uphawu "-" uma ufuna injini yokusesha ukuthola amakhasi anegama elilodwa lokusesha, kodwa udinga injini yokusesha ukukhipha amanye amagama ahlotshaniswa nalolo gama lokusesha. Ngokwesibonelo:
- Superman -Krypton
Utshela izinjini zokusesha ongathanda ukuthola amakhasi anegama elithi "Superman", kodwa ungafaki uhlu olufaka ulwazi mayelana ne "Krypton". Lena indlela elula futhi elula yokuqeda ulwazi oluthe xaxa futhi unciphise usesho lwakho phansi; plus ungenza uchungechunge lwamagama akhishiwe, njengalokhu: superman -krypton - "lex luthor".
- Uphawu lokuhlanganisa:
Manje ukuthi uyakwazi ukuqeda amagama okusesha, nansi ukuthi ungawafaka kanjani, usebenzisa uphawu "+". Isibonelo, uma unemigomo okufanele ibuyiselwe kuyo yonke imiphumela yakho yosesho, ungafaka uphawu oluphambili ngaphambi kwemigomo okudingeka uyifake, njenge:
- ibhola + nfl
Imiphumela yakho yosesho manje ingabe nayo yonke le mibandela ifakiwe.
Okuningi mayelana ne-boolean
Khumbula ukuthi akuzona zonke izinjini kanye nezinkomba ezisekela imigomo ye-Boolean. Kodwa-ke, iningi liyakwenza, futhi ungakwazi ukuthola kalula ukuthi yini ofuna ukuyisebenzisa isekela le nqubo ngokubonisana ne-FAQ's (Imibuzo Evame Ukubuzwa) ku-injini yokusesha noma ikhasi lasekhaya lomhlahlandlela.
Ukubizwa ngegama: BOO-le-un
Futhi eyaziwa ngokuthi: i- Boolean, ilogi ye-boolean, usesho lwe-boolean, ama-boolean opharetha, ama-boolean, incazelo ye- boolean , ukusesha kwe- boolean, imiyalo ye-boolean
Izibonelo: Ukusebenzisa nokunciphisa usesho ngokuhlanganisa amagama; it uzothola amadokhumenti asebenzisa kokubili amagama osesho owakushoyo, njengalesi sibonelo:
- I-Portland ne-Oregon
Ukusebenzisa OR ukwandisa usesho ukufaka imiphumela equkethe noma yiziphi amagama othayiphayo.
- inkululeko noma i-democrat
Ukusebenzisa i-NOT kuzosula ukusesha ngokungabandakanyi amagama athile okusesha.
- Oregon Awuhambi
Ukusesha kwe-Boolean: Okuwusizo Wokusesha Okuphumelelayo
Ubuchwepheshe bokusesha bobukhoma kungenye yezingqinamba eziyisisekelo ngaphansi kwezinjini zokusesha zanamuhla. Ngaphandle kokuqaphela, sisebenzisa ngokunenzuzo inqubo yokucinga elula cishe njalo lapho sibhala ngombuzo wosesho. Ukuqonda inqubo nolwazi lwe-Boolean ukusesha kuzosinika ubuchwepheshe obudingekayo esikudingayo ukwenza usesho lwethu luphumelele nakakhulu.
