we are using GCP Dialog flow CX for building BOT for the purpose of automatic query resolve with predefined agent configurations. The user input is an alpha numeric which consists of 2 letters followed by 7 digits. The issue we are facing is, BOT wrongly understanding the letters thus giving invalid results. For example,
KE-565220 --> working TH-146681 --> working
UP-112404 --> Not working, bot understood as GP-112404 AF-958174 --> Not Working, bot understood as FJ-958174
Please suggest us a way to increase the accuracy in identifying the letter correctly. Appreciate your help.
