One problem with Tax Almanac's yellow search box, is that it produced a long list of results sorted in some sort of order. I think the thread with the last response was at the bottom of the list. Not sure, exactly. Anyhow, once the search results were produced in TA, now you are going to be spending some time going through each discussion. Some were just a single question that was never answered. Some were a long thread that ebbed and flowed through various subjects, even off subject. Some were not even close to what you were searching for. It took a while to find that jewel.
Some of this was likely due to the search terms that were used. But a lot of the problem was just due to the simplicity of TA structure.
The Advanced Search on this site is really good. If you have not used it, then you need to check it out. Also, the 'search within results' makes it even more outstanding.
On other sites, I have seen where the search results produce a % Relevancy indicator. I can never figure out how they know this, but for the most part they do seem to get it right. Is this site able to produce that?
