let's say memberA wants to look for pictures of sandwiches (the food)

• they do a search for sandwich

• and find whatever's going on with the search results there

(search returns 2 posts, wiki count says ~50)

Sandwich was aliased to sandwich_(disambiguation)

there's a sandwich_(food) tag for the food

So our hypothetical memberA, if they were not aware of any of that, has to do the following to find their pictures of food sandwiches:

• 1. search for sandwich
• 2. find no relevant results
• 3. check the wiki/ask on the forums/elsewhere
• 4. follow the link to sandwich (disambiguation)
• 5. find the sandwich (food) tag
• 6. use that tag to search for whatever they were looking for

This is assuming any one of the following:

• they are aware that this is anomalous desired behaviour
• they are determined enough to get an answer
• they know about the wiki, and implications/aliases
• they have a basic understanding of how either work
• they're still motivated to use the newly-found tag

The entire above dilemma could be avoided if sandwich wasn't aliased, and manually moved into the (disambiguation) tag

That way, the basic tag most people would use first still works for searches, albeit less specifically
