# Search for any variable

Well this hit me after spending a really long time searching for a post I was viewing two days ago. I couldn't understand why can't I find it. I was trying to remember what was written in the title so I could search for it, but any of the queries I tried couldn't get me there.
At one point I thought it was maybe deleted, and just before giving up, I thought about trying changing to a different variable letter - guess what, there it was.

Now this is something you can find for yourselves. Searching $"\frac{1}{a}"$ ,for example, will generate an amount of 3,659 results. On the other hand, searching for $"\frac{1}{x}"$ will generate a totally different set of results with the amount of 16,521! (And this is by the time this was written of course)

Now I know those are two different letters and that it is more common to use one instead of the other for certain expressions, but I can't avoid thinking about all the results I'm missing(?) As for duplicates too I guess this issue is not being very helpful.

How about setting the priority for the letter that was written while also keeping the other results of similar expressions? Or any other option that will benefit the search?

I think the problem is that this site uses the same text-oriented search engine as every other Stack Exchange site, and to it $\frac1a$ and $\frac1x$ are two very different queries.
• If I asked a "math-oriented" search engine for $\zeta(s)$, and got back every instance of $a(b)$ for all symbols $a$ and $b$, I would not be happy. – Gerry Myerson Oct 27 '15 at 4:39
• @GerryMyerson Alright, so "zeta(s)" works. For code that's already latex-formatted. A math-oriented search engine could do that too, since zeta is not a single-letter variable name. However, searching for "zeta(s)" does not find any instances of, say, unicode versions, "ζ(s)". Also, searching for "ζ(s)" yields 0 results. Not that it makes that big of a difference, but just saying. – Alex Mar 7 '16 at 20:24
