A search term can be specified to be case-sensitive or to match a whole word by checking the respective options in the Options pane (see screenshot below). If you wish to search using a regular expression, check the Regular Expression option in the Options pane before clicking the Find Next or Find All button. See below for more details about using regular expressions.
|Note:||A whole word is considered to be delimited by any character that is not alphanumeric or the underscore character. So the search term asset will return the text xbrl:asset, since the colon character (:) is considered to be a word delimiter.|
In the Types pane, specify the components to be searched.
You can use regular expressions to further refine your search criteria. A pop-up list is available to help you build regular expressions. To access this list, click the > button to the right of the input field for the search term.
Clicking on the required expression description inserts the corresponding expression syntax character in the input field. Given below is a list of regular expression syntax characters.

Marks the start of a region for tagging a match.
Marks the end of a tagged region.

Matches 0 or more times. For example, Sa*m matches Sm, Sam, Saam, Saaam and so on.

For example, Sa+m matches Sam, Saam, Saaam and so on.
