Kukho imigaqo emibini yokusisiseko yaseBoolean exhaswe kwiGoogle: KUNYE no- OR , kwaye bathetha nje oko bathetha ukuba bathetha.
Ungasebenzisa ukukhangela kweBoolean ukukunceda ukuba uchaze ukuba ufuna ukufumana ntoni, nokuba uyayenza ngakumbi ngakumbi (usebenzisa i- AND ) okanye ngaphantsi (oko kukuthi yiyiphi i- OR ).
Ukusebenzisa i-Boolean Operator
Sebenzisa kunye nophando kwiGoogle ukukhangela yonke imigaqo yophando oyicacisayo. Ku luncedo ukusebenzisa i-AND ngenkathi ufuna ukuqiniseka ukuba isihloko ophanda ngayo empeleni siza kusifumana kwiziphumo zophando.
Njengomzekelo, tshela ucinga igama elithi Amazon kwiGoogle. Iziphumo ziza kubonisa izinto kwi-Amazon.com, njengekhasi lokuqala lasekhaya, i-akhawunti yabo ye-Twitter, i-Amazon Prime information kunye nezinye izinto ongazithenga kwi-Amazon.com.
Nangona kunjalo, ukuba ukhona kunokuba ufuna ulwazi kwihlathi laseAmazon, nokuba ufune amahlathi e-Amazon angakunika iziphumo ezimalunga ne-Amazon.com okanye igama elithi "Amazon" ngokubanzi. Ukuqinisekisa ukuba isiphumo ngasinye sophando sichaza zombini amagama athi "ama-Amazon" kunye "namahlathi," ufuna ukusebenzisa umqhubi we-AND.
U mzekelo:
- Ama-Amazon kunye namahlathi emvula
- isobho kunye nama-biscuits
- iindaba kunye nemfazwe nomongameli
Ukusebenzisa i-OO Boolean Operator
I-Google isebenzisa OKANYE umqhubi ukuba afune ixesha elinye okanye elinye . Oku kuthetha ukuba eli nqaku linokuthi liqule igama kodwa akufuneki ukuba liquke zombini. Oku ngokuqhelekileyo isebenza kakuhle xa usebenzisa amagama amabini afanayo okanye amagama angatshintshana.
Abanye ababhali bayakukhetha igama elithi "draw" endaweni "yeskripthi" xa uthetha ngemidwebo, umzekelo. Kule meko, kuya kuba luncedo ukuxelela iGoogle ukuba awukhathaleli liphi igama elisetyenziselwayo kuba zombini zithetha ngokufanayo into efanayo.
Uyabona ukuba OKANYE umsebenzisi uhlukile kwi-ANDI xa uqhathanisa iziphumo zokudweba OKANYE ukupenda ngokubhekiselele kwendlela yokudweba nokupenda. Ekubeni umntu wangaphambili unika i-Google inkululeko yokukubonisa umxholo ophezulu (ukususela ngeliphi igama elingasetyenziselwa), kukho iziphumo ezingakumbi kunokuba ukhawuleza uphendlo olufunekayo emabini amagama (njengomzekelo KUNYE nomzekelo).
Ungasebenzisa kwakhona umgca (|) umgca endaweni ye-OO (yinto ehambelanisiweyo kwinqhosha le-slash phambili).
U mzekelo:
- indlela yokudweba OKANYE ukupenda
- i-ORAL okanye i-peleo zokupheka
- obomvu okanye obunxantathu
Indlela yokudibanisa i-Boolean Search and Use Phrases
Ukuba ucinga ibinzana kunokuba ligama elilodwa, unokwenza iqela lamagama kunye namanqaku okucaphuna.
Ngokomzekelo, ukukhangela "iibhisikidi ze-sausage" (kunye neengcaphuno ezibandakanyiweyo) ziza kubonisa kuphela iziphumo zegama elibandakanya amagama ndawonye ngaphandle kokunye phakathi kwabo. Iyakuthi iyayihoxisa amabinzana afana ne- sausage kunye nama-biscuits .
Nangona kunjalo, usebenzisa "ama-biscuits" "i-sauce ishizi" iya kunika imiphumo yegama elifanelekileyo, ngoko uya kufumana amanqaku athetha nge-sauce yeshizi kodwa kunye nama-biscuits e-sausage.
Ukuba ufuna iincinci ezingaphezulu kweyodwa okanye igama elingundoqo ukongeza kwi-Boolean, unokuziqhawula ngeakhasethi, ezifana ne- recipes gravy (sausage | bhisikidi) ukukhangela iipeshi zokupheka ngamasikeji okanye ama-biscuits. Ungakwazi ukudibanisa amabinzana athile kwaye ufune "i-bhisikidi yesobho" (recipe | ukuhlaziywa) .
Ukuze ulandele kule mzekelo, ukuba ufuna ukuqiniseka ukuba zonke iziphumo zeGoogle zibonisa iindlela zokupheka ezenziwe nge-paleo ezibandakanya ushizi, umzekelo omnye unokukuthayipha (kunye neempendulo) "iresiphi ye-paleo" (isobho kunye noshizi) .
