Precautions when searching for F-terms (additional code)
Some of the F-terms used for patent search have a symbol called "additional code" at the end.Example: "2E110GA32W" ("W" at the end is an additional code).
Creating a search expression without knowing that the additional code has been added can lead to unexpected results.
Therefore, I will introduce how to check the additional code and points to note when creating a search formula using F-term.
