+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)

2019-03-13 How to Generate a CAN FD Frame with BRS Enabled
Question: How can I activate the Bit Rate Switch (BRS)? Answer: The BRS bit decides whether the optional higher bit rate in the data phase of a CAN FD frame is used. Both, arbitration and data phase bit rate are configured in the Network Hardware Configuration. If a DBC database is used...

2019-07-15 Importance of the Sample Point Configuration in a CAN FD Network
The correct sample point configuration is very important with CAN FD networks. The reason is the Bit Rate Switch (BRS). In order to indicate a switch of the bit rate the BRS bit is sent recessively. The first part of a CAN FD frame, until the BRS bit is transmitted with the NOMINAL BIT RATE. The...

2020-05-13 Converting a CAN Database into a CAN FD Database
Question: How to modify a CAN database so it can be used to send CAN FD frames on a CAN FD bus? Answer: CAN FD frames (messages) require some additional attributes compared to CAN frames. These attributes need to be added to the database. The template CAN_FD Template.dbc contains the...
