# Field content selector

{% hint style="warning" %}
This information is outdated. Please help to improve it.
{% endhint %}

This feature allows you to store a selection of often-used words or phrases that you use often in your database. By default it is enabled for the fields *Journal*, *Author*, *Keywords* and *Publisher*, but you can also add selectors to other fields, in the upper part of the *Manage* dialog (menu **Options -→ Manage content selectors**).

The word selection is database-specific, and is saved along with your references in the .bib file.

To add a new word in the entry editor, you can simply click into the text box for the field for which you configured the selectors. A drop down menu will appear and you can select the keyword of your choice. This mechanism is based on the autocompletion functionality in JabRef. Therefore, you need to have autocompletion enabled in your preferences.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jabref.org/v4/fields/contentselector.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
