How to replace text that is only exact match

[Isaac Goh]

Have thousands of lines starting with Index 0 to Index 1000
I only want to replace specific line e.g. index 10 and not Index 100 or Index 101 or Index 102
When I input (Index 10) in the Find What: box and
input (\1)\t(\2ok) in Replace with: box and click Replace All, Beside Index 10, It will include Index 100-109 and all those starting with Index 10… Is there any quote or symbol used to only specific a text with exact match, thanks.
