Search Tips

• Enter one or more keywords.
• Searches are not case sensitive.
• Use the asterisk (*) as a suffix wildcard character in keywords.
  Example: enter filter* to find documentation with keywords such as filter or filters or filtering
• Use quotes to find an exact phrase.
  Example: "filter coefficient"
• Enter multiple keywords, such as lowpass filter, or a Boolean expression, using AND, OR, and NOT.
• Entering lowpass filter is the same as entering lowpass and filter.
  Note: multiple keywords entered without a Boolean use the AND expression.
• Use an expression such as lowpass or bandpass to find documentation containing either keyword.
• You can also use parentheses in Boolean expressions.
  Example: (lowpass and equiripple) or hanning
• Use the NEAR operator to find keywords that appear near each other.
  Example: enter lowpass near equiripple to find documents with lowpass and equiripple appearing near one another
• Besides using NEAR operator, you can specify how close keywords could be.
  Example: enter "lowpass w/5 equiripple" (with quotes) to find documents where lowpass and equiripple appear within a frame of 5 words, or "w/7 lowpass equiripple filter" to find lowpass, equiripple, and filter within a 7-word frame. Common words are not counted as part of word frame.
