# Using Wildcards in Text Searches

Wildcards or placeholders can be used to search for some unspecified or even invisible characters.

You can use wildcards when you find and replace text in a document. For example, "s.n" finds "sun" and "son".

1. தொகு - கண்டுபிடி & மாற்றிவை ஐத் தேர்ந்தெடுக.

2. Click More Options to expand the dialog.

3. வழக்கமான வெளிப்பாடுகள் தெரிவுப் பெட்டியைத் தேர்க.

4. In the Find box, type the search term and the wildcard(s) that you want to use in your search.

5. அடுத்தைக் கண்டுபிடி அல்லது அனைத்தையும் கண்டுபிடி ஐச் சொடுக்குக.

## Regular Expression Examples

1. The wildcard for a single character is a period (.).

2. The wildcard for zero or more occurrences of the previous character is an asterisk. For example: "123*" finds "12" "123", and "1233".

3. The wildcard combination to search for zero or more occurrences of any character is a period and asterisk (.*).

4. The wildcard for the end of a paragraph is a dollar sign ($). The wildcard character combination for the start of a paragraph is a caret and a period (^.).

5. The wildcard for a tab character is \t.

A search using a regular expression will work only within one paragraph. To search using a regular expression in more than one paragraph, do a separate search in each paragraph.
