TrigramWordBase

This class represents a database function used to calculate the trigram similarity between a specific string and a given expression. It initializes with a string value and an expression, ensuring the input string is treated as a value if it does not already support expression resolution. The function typically returns a floating-point value representing the similarity score.

Attributes
