Hello,
I'm trying to make an item search engine in a treeview, if I do it with a button, it works for me.

But I want to do the search without a button, just writing in the entry I select the closest thing.

I have done this, it does not give me any errors or anything, but it does not select any similar item or anything.

Python
self.entry_buscador = tk.Entry()
        self.entry_buscador.place(x=150, y=142, width=450, height=40)

self.entry_buscador.bind("<<KeyRelease>>", self.buscar)

def buscar(self, event):
        self.query = self.entry_buscador.get().lower()

        for item in self.treeview_almacen.get_children():
            values = self.treeview_almacen.item(item, "values")
            if self.query in values[0].lower():
                self.treeview_almacen.selection_set(item)
                self.treeview_almacen.focus(item)
                self.treeview_almacen.see(item)
            else:
                self.treeview_almacen.selection_remove(item)

You need to use the debugger to trace through the event handler to see what is happening.

Your code is close but not enough information given. I have done some modifications to make sure the set-up is done correctly. I have also added dummy data as items to test.

You will need both the 'tkinter' and 'ttk' modules -
Python
import tkinter as tk
from tkinter import ttk

class ItemSearchApp:
    def __init__(self, root):
        self.root = root
        self.root.title("Item Search Engine")

        #Create your Treeview...
        self.treeview_almacen = ttk.Treeview(root, columns=("item_name"))
        self.treeview_almacen.heading("item_name", text="Item Name")
        self.treeview_almacen.pack()

        #Create your Entry widget for search options...
        self.entry_buscador = ttk.Entry(root)
        self.entry_buscador.pack()
        
        #Bind the key release event to your search function...
        self.entry_buscador.bind("<KeyRelease>", self.buscar)

        #I have added sample data for the Treeview...
        self.populate_treeview()

    def populate_treeview(self):
        #Insert some sample items into the Treeview...
        items = ["Apple", "Banana", "Orange", "Pear", "Grapes", "Pineapple"]
        for item in items:
            self.treeview_almacen.insert("", "end", values=(item))

    def buscar(self, event):
        self.query = self.entry_buscador.get().lower()

        #Loop through Treeview items...
        for item in self.treeview_almacen.get_children():
            values = self.treeview_almacen.item(item, "values")
            if self.query in values[0].lower():
                self.treeview_almacen.selection_set(item)  #Select the matching item...
                self.treeview_almacen.focus(item)  #Focus on the matching item...
                self.treeview_almacen.see(item)  #Scroll to make the matching item visible...
            else:
                self.treeview_almacen.selection_remove(item)  #Deselect non-matching items...

#Create your main application window...
root = tk.Tk()
app = ItemSearchApp(root)
root.mainloop()


And voila, this should work for you.
