Kunemithetho emibili yokusesha ye-Boolean eyisisekelo esekelwe ku-Google: KANYE no- OR , futhi basho lokho abakushoyo ukuthi basho.
Ungasebenzisa ukuseshwa kwe-Boolean ukusiza ukuthi ucacise ukuthi yini ofuna ukuyifumana, kungakhathaliseki ukuthi yenza okucacile (usebenzisa i- AND ) noma ngaphansi okucacile (yilokho okushiwo OK ).
Ukusebenzisa i-AND Boolean Operator
Sebenzisa futhi ukusesha ku-Google ukucinga wonke amagama osesho owucacisayo. Kuyasiza ukusebenzisa i-AND uma ufuna ukuqinisekisa ukuthi isihloko ohlolisayo empeleni sihloko ongayithola emiphumeleni yokusesha.
Isibonelo, tshela usesha igama elithi Amazon ku-Google. Imiphumela ingase ikubonise izinto ku-Amazon.com, njengekhasi eliyisiqalo sesayithi, i-akhawunti yabo ye-Twitter, i-Amazon Prime ulwazi kanye nezinye izinto ongazithenga ku-Amazon.com.
Kodwa-ke, uma ngabe kunokuba ufune ulwazi emahlathini ase-Amazon, ngisho nokufuna amahlathi e-Amazon angakunika imiphumela ephathelene ne-Amazon.com noma igama elithi "Amazon" ngokujwayelekile. Ukuze uqinisekise ukuthi umphumela ngamunye wokusesha uhlanganisa amagama athi "i-Amazon" nethi "amahlathi", ufuna ukusebenzisa i-ANDER operator.
Izibonelo:
- I-Amazon ne-rainforest
- isobho kanye nama-biscuits
- izindaba nempi nomengameli
Ukusebenzisa i-OR Boolean Operator
I-Google isebenzisa i-OU opharetha ukucinga igama elilodwa noma elinye . Lokhu kusho ukuthi lesi sihloko singaqukatha noma yiliphi igama kodwa akudingeki lihlanganise kokubili. Lokhu kuvame ukusebenza kahle uma usebenzisa amagama amabili afanayo noma amagama angashintshashintshayo.
Abanye ababhali bazokhetha igama elithi "draw" esikhundleni sokuthi "udwebe" lapho ukhuluma ngemidwebo, isibonelo. Kulokhu, kungaba usizo ukutshela iGoogle ukuthi awukhathaleli ukuthi yiliphi igama elisetshenzisiwe ngoba bobabili basho ngokuyisisekelo into efanayo.
Ungabona ukuthi i-OU opharetha ihluke kanjani ku-NAKHO uma uqhathanisa imiphumela yokudweba noma udweba kanjani ukudweba nokudweba. Njengoba owokuqala unikeza i-Google inkululeko yokukubonisa okuqukethwe okuningi (kusukela noma yiliphi igama elingasetshenziswa), kunemiphumela eminingi kakhulu uma ukhawulela usesho oludingayo kokubili amagama (kufana nesibonelo).
Ungasebenzisa futhi uhlamvu lwe-break (|) esikhundleni se-OR (yilo oluhlanganiswe ukhiye wokugqama ophambili).
Izibonelo:
- indlela yokudweba noma ukudweba
- okuyinhloko noma i-paleo zokupheka
- unobomvu obomvu noma ophuzi
Indlela Yokuhlanganisa Ukufundwa Kwe-Boolean nokusebenzisa Imibhalo Eqondile
Uma uhlola ibinzana kunokuba nje igama elilodwa, ungakwazi ukuhlanganisa amagama kanye namamaki okucaphuna.
Ngokwesibonelo, ukucinga "amabhisikidi wesobho" (kanye namacaphuno afakiwe) kuzokhombisa imiphumela yemishwana ehlanganisa amagama ndawonye ngaphandle kokunye phakathi kwabo. Kuzokwenqabela imishwana efana ne- sausage ne-cheese biscuits .
Noma kunjalo, usebenzisa "amabhisikidi" "ushukela ushizi" uzonikeza imiphumela yegama elilodwa, ngakho-ke uzothola izihloko ezikhuluma ngosuzi ushizi kodwa futhi amabhisikidi wesobho.
Uma uhlola okungaphezu kweyodwa ibinzana noma igama elingukhiye ngaphezu kwe-Boolean, ungawahlanganisa ngama-parenthesis, njengama- recipe gravy (isisisisi | ibhisikidi) ukucinga zokupheka ze-gravy ngamasekisi noma ama-biscuits. Ungakwazi ngisho ukuhlanganisa imishwana eqondile futhi ufune "ibhisikidi yesobho" (iresiphi | ukubuyekezwa) .
Ukuze ulandele kule sibonelo, uma ufuna ukuqinisekisa ukuthi yonke imiphumela ye-Google ibonisa izindlela zokupheka ze-paleo ezibandakanya ushizi, isibonelo esisodwa singase uthayiphe (ngezingcaphuno) "iresiphi ye-paleo" (isobho kanye noshizi) .
