I clicked on "Search" above, and entered: HST
Exactly that - just the one entry.

The result: There are no results for your query. Please try a broader range of search criteria.

But we know that there are entries for this topic!

So, how does the Search really work?

Hi, Samuel,

You're right. Our Webmaster just did some 'tweaking' for you. Please try your search again. You should find that both HST and +HST return many results.

Thanks for bringing this to our attention.

Hey - good job!

In the past I used the Search with limited success. Testing it now yields a much better response.
Whatever the Webmaster did - keep it up and thanks.

Response is better but still problematic.
I found a post from 2006 that includes both EDI and Edisoft.
But searching for +EDI+Edisoft for the last 5 years yields nothing.
Searching for +EDI or + EDI yields lots of entries that have edi somewhere within a word.
Is there a way to search for an appearance of EDI only when there are spaces before and after those letters?

Not only does the simple Search seem to work well (especially using literal strings with spaces), there is a Find (ctrl-F) within a topic.

Wally just provided the answer to the last question.

Use quotes with a space after the word but not before it.

I like the highlighting of the relevant word.

I especially like being able to enter an odd topic, like "EDI " in the first search box, without having to go to advanced, and seeing lots of results.

+EDI => 200 results
+" EDI " => 23 results
