Yog li ntawd, cov neeg ua haujlwm Boolean yog dab tsi thiab lawv ua haujlwm li cas?
Boolean cov neeg ua haujlwm yog cov lus uas txuas cov ntsiab lus tshawb nrhiav (keywords) rau tsim ib lo lus logic uas ib tug database ua tau nkag siab. Lawv tso cai rau koj rau tsim ib tug complex nrhiav uas ua tau suav nrog ntau lub ntsiab lus thiab lwm lo lus tseem ceeb. Nrhiav cov khoom uas siv ob lo lus tseem ceeb. Nrhiav cov khoom uas siv ob qho ntawm cov ntsiab lus.
