Type the word or phrase you seek into the text-entry box. Think of a word as a combination of letters and numbers. You can tell SpiderMonkey how to distinguish words and numbers you want treated differently. If you want to find an exact phrase or full name use " quotation marks" around the phrase when you enter words in the search box. This tells SpiderMonkey to match your word pattern exactly and search for your phrase set out in quotation marks.
You can ban or prioritize words using (not) or (-). You can also indicate must-have words with (and) or (+). If you want to search for a word or phrase but want SpiderMonkey to exclude pages having certain words, simply type: "my_word and my_otherword not this_word". For more examples click robot.
