## `Simple` search

It is possible to perform a `simple` keyword search.

For example, if you search for the following keywords `apple`

GLPI will automatically add a `*` (except if `*` is already present) `apple*`

GLPI will then search for all articles that contain words such as `apple`, `apples`, `applesauce`, or `applet`.

## `Complex` search

The search engine of the knowledge base also offers the following operators for a complex search

### Behaviors

Here are some examples:

| Search                             | Descritpion                                                                                                                                                                                                                                                                                        |
| ---------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`+apple +juice`**                | Finds articles that contain both words.                                                                                                                                                                                                                                                            |
| **`+apple macintosh`**             | Finds articles that contain the word "apple", but ranks articles higher if they also contain "macintosh".                                                                                                                                                                                          |
| **`+apple -macintosh`**            | Finds items that contain the word "apple" but not "macintosh".                                                                                                                                                                                                                                     |
| **`+apple ~macintosh`**            | Finds articles that contain the word "apple", but if the line also contains the word "macintosh", rank it lower than if the line does not contain the word "apple". This method is "gentler" than the "+apple -macintosh" search, where the presence of "macintosh" causes the line to not return. |
| **`+apple +(>turnover <strudel)`** | Finds articles that contain the words "apple" and "turnover", or "apple" and "strudel" (in any order), but ranks "apple turnover" higher than "apple strudel".                                                                                                                                     |
| **`apple*`**                       | Finds articles that contain words like "apple", "apples", "applesauce", or "applet". Note that the `"` characters surrounding the expression are characters that delimit the expression. They are not the quotation marks that surround the search string itself.                                  |
