How to file type limit content search? Ex. IN *.htm* find word "étant"

RE: How to Make Windows 7 Search File Contents: 12 Steps

OK I have enable Win7 content search, but when I open Explorer to a desired directory and do CTRL+F I see the normal search window.

How do I search for instance within all htm(l) extended file, for all the files containing the word "étant" and "étang".

If I directly search for my content key words, the search will return all the file times, viz doc, xls, htm*, ...

Thanks

ext:htm AND ext:html

No search string "étant ext:htm AND ext:html" or even "ext:htm AND ext:html"
returns no results
While earch string "étant", do list all files containing the word "étant"
