# Index Pages

Index pages are gateways to EMS server properties pages. These pages list the item definitions for a entity category. For example, there is a topics index page that lists all topics defined for the EMS server:

This section describes features common to all index pages.

## Viewing an Item

To view an item in the list, click its name.

## Filtering the List

To view a subset of the items, type characters in the Filter or Create field. The list narrows to display only those items that contain the character sequence in their names.

Filters accept standard Java regular expressions using standard JavaScript regular expressions (we present a subset of the details in the following table).

Syntax | Description
--- | ---
JavaScript Regular Expression Filtering
. (dot) | Match any single character.
* (star) | Match zero or more instances of the preceding element.
+ (plus) | Match one or more instances of the preceding element.
`\w` | Match any word character.
[chars] | Match any single instance of the characters within square brackets.

## Creating a New Item

To create a new item, type its name in the Filter or Create field, then click the Create button or type the Enter key. The new item is created, and the relevant properties page opens. (This operation is available only when you own the lock for the EMS server; see Locking the Server)

## Duplicating an Item

To duplicate a definition (as a starting point for defining a similar item) click Duplicate . The browser immediately displays the duplicate item in the relevant properties page for editing. (This operation is available only when you own the lock for the EMS server.)

## Deleting a Item

To delete a definition, click Delete corresponding to the definition. (This operation is available only when you own the lock for the EMS server.)
