algorithm go pattern-matching Go

I've encountered a strange issue with I'm following best practices but I'm a bit lost with I'm trying to implement I'm learning this framework and I'm not sure how to approach I'm currently working on an implementation of the Aho-Corasick algorithm in Go to efficiently search for multiple patterns in a large text... However, I'm experiencing unexpected behavior where certain patterns are not being matched, even though they should. My implementation utilizes the `go-aho-corasick` library, version 0.5.0, but I'm not seeing the expected results. Here’s a simplified version of my code: ```go package main import ( "fmt" "github.com/crazypanda/go-aho-corasick" ) func main() { keywords := []string{"he", "she", "his", "hers"} ac := ahocorasick.New() for _, word := range keywords { ac.Add(word) } ac.Build() text := "ushers" matches := ac.FindAll([]byte(text)) for _, match := range matches { fmt.Printf("Matched: %s at position %d\n", text[match.Start:match.End], match.Start) } } ``` When I run this code, I only get the output for the pattern "she" but not for "he" or any other patterns. I’ve double-checked the input text and the keywords, and they should all match based on the content. I also verified that the `go-aho-corasick` library is set up correctly and that the `Build` method is called after adding all patterns. As a troubleshooting step, I replaced the input string with "he he he" to see if that would yield a different result, but still, only "she" shows up as a match. Additionally, I've tried running the same algorithm in Python using the `pyahocorasick` library, and it correctly identifies all patterns. I'm beginning to wonder if there’s a subtle scenario with how I’m using the Go library. Has anyone encountered similar issues with the Aho-Corasick implementation in Go, or does anyone see any potential mistakes in my approach? Any insights would be greatly appreciated! I'm open to any suggestions. For reference, this is a production microservice. What's the correct way to implement this? I'm developing on Windows 10 with Go. Any suggestions would be helpful. My development environment is Windows 10. I'm coming from a different tech stack and learning Go. Is there a simpler solution I'm overlooking?
