With search by LPs, you can find the recognized license plates in the archive, as well as filter them according to specified criteria.

To search by license plates, do the following:

1. Set a search interval (see Setting a search interval).
2. From the Detection drop-down list, select the detector, the events from which you want to use as a search criterion.

3. In the Enter text field, enter the license plate that you want to find. You can enter either a full license plate or a part of it using the ? character (any character in the license plate) and the * character (any number of any characters in the license plate). For example, a search query ?20* shows all vehicles with license plates containing 2 and 0 in the second and third positions, respectively. License plates can contain any number of characters.

   To search by all recognized license plates, enter * (asterisk).
