2. Inezinhlobonhlobo zezinhlelo zokusebenza: sishilo ukuthi kunezinhlobo eziningi zemishini yokuqhumisa isibhamu ukuze ivumelane nezimo zokusebenza nezidingo ezahlukene. Uma kuqhathaniswa neminye imishini yokudubula, yethuumshini wokuqhumisa umshini wokukhasainohlu olubanzi lwezinhlelo zokusebenza futhi ingahlangabezana nezimo ezihlukene zomsebenzi kanye nezidingo. Umshini wokuqhumisa isibhamu se-crawler unezivinini ezintathu ezihlukene ukuze u-opharetha azikhethe, ezifanele izidingo zokukhiqiza izinto ezihlukene futhi ongafinyelela umphumela olindelekile. Kungashiwo ukuthi ukuba nesethi yemishini eqhumayo yokudubula kufana nokuba nemishini yokudubula eminingi yezinhlobo ezahlukene. Impilo yesevisi ebanzi futhi ingenye yezinzuzo eziyinhloko zemishini yokuqhuma isibhamu se-crawler shot.
3. Ukusebenza kahle okuphezulu: Isizathu esenza abakhiqizi abaningi bezimboni bakhethe ukusebenzisaumshini wokuqhumisa umshini wokukhasakungenxa yokusebenza kahle kwayo okuphezulu. Umehluko phakathi komshini wokuqhumisa isibhamu sokudubula neminye imishini yokudubula ukuthi isebenzisa indlela yokusebenza yesihlukanisi, esingahlukanisa ngempumelelo izinhlobo ezahlukene zemikhiqizo. Ngale ndlela, umkhiqizo ofanayo ungacutshungulwa ngesivinini esithile, bese uhlangabezana nezidingo zomsebenzi ophumelelayo. Amandla okusebenza omshini oqhumisayo wokudubula aqine kakhulu, okungenye yezinzuzo zawo eziyinhloko.
Okungenhla yizinzuzo ezintathu ezinkulu ze-umshini wokuqhumisa umshini wokukhasa. Inempilo ende yesevisi futhi inciphisa izindleko, ingasetshenziswa ezindaweni eziningi zokusebenza, futhi inokusebenza kahle kakhulu komsebenzi.
