Search Tips

1. Enter one or more keywords.
2. Searches are not case sensitive.
3. 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.
4. Use quotes to find an exact phrase.
   Example: "filter coefficient".
5. Enter multiple keywords, such as lowpass filter, or a Boolean expression, using AND, OR and NOT.
6. Entering lowpass filter is the same as entering lowpass and filter.
   Note: multiple keywords entered without a Boolean use the AND expression.
7. Use an expression like lowpass or bandpass to find documentation containing either keyword.
8. You can also use parentheses in Boolean expressions.
   Example: (lowpass and equiripple) or hanning.
9. Use 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.
10. 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.
11. Error Messages
    Error occurred. Do Ctrl-Refresh/Reload. See Error Messages in Search Tips below.
    This error typically occurs when you open the Search page, go to a different page, then reopen the Search page and search for a keyword or phrase.
    
    Workarounds:
    
    1. Do a Ctrl-Refresh to refresh the Search page, make sure the "show in new window" option is checked, then re-enter the query. If this does not work, close all browser windows, and reopen RFDE Help (Help > RF Design Environment Documentation).
    
    
    2. To avoid this error, open two RFDE Help windows. Open the first one and open the Search page in it, then continue to use this window only for searches and opening topics from the list of results. Open a second RFDE Help window and use it only to navigate through the documentation.
