If the text can be anywhere on the page, then:
the boolean false is a flag if you want to you Regex (Regular Expression). In other words, you need something similar to your text but not exact. You should use the false unless you know specifically that you need to use Regex–because you need to know the components that make up Regex.
I use Regex to get the seconds on our page timestamp. Notice the asterisk after the Date and the Regex value is true.
WebUI.verifyTextPresent('Last Updated by ' + GlobalVariable.gUserName + ' on ' + GlobalVariable.gFormattedDate + ' .*', true)
If you want to get the text of a specific element, then you can use:
If your element is a textarea or input, there is also the possibility of the below:
WebUI.verifyElementAttributeValue(findTestObject('yourTO'), "value", 'yourElementsText', 10)
If you need to use Regex with the last two statements, then you could combine two statements as one: verifyMatch and getText or getAttribute.
