Find using containing text

I am searching some *.html files using "containing text finding" method.

I have tried several times,but no results came out.

I've also tried the windows intrinsic searching tools, it works well.

How come? What's wrong with my DO?Can anybody help me?

Profuse thanks in advance.

Opus searches the HTML source, not the text that the source renders, so if there are tags breaking up the words you are searching for, or they are encoded using &-style sequences or similar, then you won't find a match.

I've got it.Thanks!
