I need search some words in Eclipse wokspace. It should be exaclty matching that word.
 I need to search `'AT'` in eclipse workspace. But when I use eclipse search for AT it gives all the results which includes AT in any word which I dont want. Later I realised that I can use regular expression in Eclipse search for matching the exact word. For that I used the following regular expression. But It does not give any result.

```
\bAT\b

```

For example : I need to Search AT. It gives the result CAT as well. I need to get the result only AT.

```
public static final String AT = "AT" ;

```

The search result gives AT,CAT,ATA,etc.. But I dont need all these results. I need only `AT`
