The Multitool provides a handy file search function for its packed files, which requires indexing the game files to be effective. In this section, we'll learn how to index files, and how to use the Index Search.

Indexing files is a simple task, so let's take a look at what you need to do:

1. In Multitool's Menubar, select Utilities -> Index -> Index Files

You'll see a progress bar appear, similar to the image on the right, pointing to the amount of files being processed, along with an estimate of how long is left before the Indexing process is completed. Once it's done, the progress bar and time estimate will disappear. You'll want to update this after major game updates, and you can opt to use the legacy Index UnpackedData Files (Legacy) instead, if you'd prefer.

The Legacy indexing method is non-performant and does not have the same benefits as the non-Legacy method. Under most circumstances, you should not use Legacy indexing.

The Index Search is a powerful tool, making use of the Index you've created. It has several filtering options, the ability to quickly open files, and fast search mode. After taking a look at the image below, we'll take a look at each of these features:

To Search your Index, type in something you want to find in the game files in the the Search Bar. In the example above, I've input PACT_BLADE. The section below the search bar will show a clickable list of each file found that contains the keyword we've searched for. When you hover over or click on one of the files, a preview of each time the string has been found in that file will display on the right. You can press the Open button above it to quickly open the file in a Text Editor or IDE.

Note that this keyword can be anything - an ID, a function name, even a random string.

In the dropdown next to the Search Files button, you'll find a wide array of filetypes you can filter your search by. By default, it will show results from all file types, but if you know what specific filetypes you're looking for (for example - you want to know every use of the PACT_BLADE status within the .khn files), you can untick the options in the dropdown.

An easy way to deselect every filetype, if you want to narrow your filtering down quickly, is to tick and untick the Select All option, which will then untick every option in the dropdown.

Next to the Filtering Dropdown, there's a Checkbox with an Up arrow icon next to it. This Checkbox controls the speed and accuracy of your search. If you want to get results faster, tick the box. In doing so, you won't always get every result you would have without the feature, but the search will go much more quickly.

This mode disables the implicit leading wildcard in the search term. Properly formatted search terms that don't require a leading wildcard (start with leading whitespace) during search will see massive performance increases.
