Hi Jonathan,
We used exactly the same method you have described for searching fields
with large text content (descriptions, comments) and tags. We used SQL
LIKE to compare descriptions, comments, etc and exact match to compare tags.
Another concern I am having is that user can type multiple words in the
tag search box. In that case, I consider each word as a separate tag and
use OR operation to combine them. But I am not exactly sure whether we
should use OR or AND here.
Thanks,
Chathura

I keep going back and forth on how tag searches should work.
If one is searching for mashups tagged with a particular tag, an exact
match seems best. For instance if I have created a query or a feed
showing mashups tagged “ok”, then I probably don’t want mashups tagged
“broken” to appear. Right now we use exact tag matching to link tags
to mashups, and if I click on a tag link “ok” I really don’t want
anything to appear that isn’t tagged with the “ok” tag.
On the other hand, when I’m searching through descriptions and titles,
I don’t generally need an exact match, but just that the search string
appears somewhere in the title or description.
Currently a custom query always match tags exactly, but descriptions
and titles loosely. When used in isolation these behaviors seem fine
but when they are combined into a single query you might occasionally
get some slightly strange results. For instance, searching for the
letter “s” in titles or descriptions returns lots of stuff, but if you
try that in tags you probably won’t get anything at all even though
many tags contain the letter “s”. Is that what you’d expect?
On the other hand, providing two ways to search tags (exact, contains)
seems more complex than it’s worth.
I guess I’m convincing myself the current behavior is fine, and the
subtle difference between searching tags and searching titles and
descriptions probably won’t be visible to an average user, but if you
have any thoughts to the contrary I’d love to hear them.
