# Search syntax

TreeSize provides a syntax that allows you to quickly and flexibly customize your search.

## Examples for a simple search

Search for photos from 2022: `Images 2022`

TreeSize will then list all image files, whether jpg, png, bmp or similar, with the modification date in 2022.

Search for large Office files: `Office > 10MB`

TreeSize lists all Excel, Word, PDF, etc. files that are larger than 10 megabytes.

## Search syntax structure

Certain keywords also offer the opportunity to formulate the search more precisely.

In addition to `file names`, you can also search for `file extensions`, `size`, `date`, `file contents` and much more.

Search terms can be combined via `AND` or `OR` and file names can be excluded from the search using the syntax.

It is also possible to use wildcards and regular expressions.

Below you will find a description of the permitted keywords and some use cases. For most keywords, there is a abbreviated form for faster search entry.

The search syntax is structured as follows:

    <Property> <Operator> <Value>

For example:

    name: = readme

This syntax finds all files that name (property) matches (operator) the word readme (value).

Several search terms can be combined:

    name:=readme, name:=movie

Or

    name:=readme OR name:=movie

Finds all files with ‘readme’ OR ‘movie’ in their name.

## All properties, operators and conjunctions

The following table shows all available properties, operators and conjunctions that you can use in TreeSize.

Note

When searching for file names, name: can be omitted. Regardless of this, the `=` character can generally be omitted as an operator, as well as `AND` as conjunction between two search terms.

These are the default property, operator, and connection values used in the search. There are different spellings for individual properties, which can be found in the table below.

Note

If you want to use reserved characters of the search syntax such as brackets, commas or spaces in the search term, the search term must be enclosed in double quotes. Examples are in the table below.

Note

A note regarding dates: When using a date as part of the search term, the required date format depends on the region settings that are configured within Windows.

### Conjunctions

### Reserved characters

When specifying values, more previsely the actual search pattern, there are various reserved characters such as wildcards or quotation marks for exact searches.

The following table lists these characters and explains them using some examples.

Example value | Description | Example | Alternative form | Results
--- | --- | --- | --- | ---
`*readme*` | Search for readme, where any number of characters can be placed before and after the word. The word contains ‘readme’. | `*readme*` | `name:=*readme*` | Finds: ‘123readme.txt’, ‘123readme.docx’ but NOT: ‘read_me.txt’, ‘reading.docx’
`readme` | Corresponds readme. The two wildcards before and after the word can be omitted for simplicity. | `readme` | `name:=readme` | Finds: ‘123readme.txt’, ‘123readme.docx’ but NOT: ‘read_me.txt’, ‘reading.docx’
`readme*` | Search for readme, where any number of characters can be placed after the word, but no characters are allowed before the word. The word begins with ‘readme’. | `readme*` | `name:=readme*` | Finds: ‘readme.txt’, ‘readme_c.docx’ but NOT: ‘123readme.txt’, ‘read_me.txt’
`*readme` | Search for readme, where any number of characters can be placed before the word, but no characters are allowed after that. The word ends with ‘readme’. | `*readme` | `name:=*readme` | Finds: ‘123readme’, ‘c_readme’ but NOT: ‘readme.txt’, ‘readme_c’
`"readme"` | Word search for the exact occurrence of the word “readme”. It searches for the exact occurrence of the word without taking parts or variations of the word into account. This means that the searched word must be present in the text as an independent and complete word in order to be recognized as a hit. | `"readme"` | `name:="readme"` | Finds: ‘readme’ or ‘readme.txt’ but NOT: ‘readmes.txt’, ‘123readme’
`rea?me` | Search for file names beginning with ‘rea’ and ending with ‘me’ and containing exactly one character in between. | none | `name:=rea?me` | Finds: ‘readme’, ‘reasme’, ‘rea1me’ but NOT: ‘rea123me’, ‘readme.txt’
`\\*readme*` | Search for files that contain the term “readme” anywhere in their path. | `\\*readme*` | `name:=\\*readme*` | Finds: “readme.txt” in any folder, “abc.doc” in “C:\temp\readme\local”. but NOT: “abc.doc” in “C:\temp\local”.
