boolean operator

基本解釋

Filter criteria are specified as the column name, followed by an equality, inequality, or Boolean operator, followed by the filter value.
過濾條件可以指定為列名，其后跟等式、不等式或布爾運(yùn)算符，然后是過濾值。
To get a more selective match for such cases, use either the enforce operator (+) or an explicit Boolean operator (AND) in the keyword search.
要在對(duì)這樣的情況使用更多選擇的匹配，需要在搜索關(guān)鍵詞中使用強(qiáng)制操作符（+）或顯式的邏輯操作符（AND）。
Applying such terms for a match might therefore need an explicit enforcement as a required term or need a combination with a Boolean operator.
因此，確實(shí)要使用這些詞匯進(jìn)行匹配時(shí)，我們需要采用顯式執(zhí)行方式，將這個(gè)詞匯作為必要詞匯或與一個(gè)邏輯操作符組合使用。

Turns out with a Boolean expression, you don't have use the equality operator equals equals, you can just say what you mean.
結(jié)果用一個(gè)bool表達(dá)式，你不需要使用等號(hào)操作符“==“了，你只要說出你的意思。
