Return search results for partial matches #159

Closed eminence closed 5 years ago

eminence commented 9 years ago

When you search for ssh you get the following results:

When you search for 'libssh' you get the following results:

When you search for libssh2 you get the following results:

With the exception of 'fleet' I expected to see all 3 results when I search for just "ssh". It seems as if the search text is being matched only on the description and not the package name?

I just wasted hours writing a crate that already existed because "tempfile" doesn't show up when you search for "temp" or "file".

azerupi commented 9 years ago

I could be wrong, but think that at the moment crates are only returned on exact match with keywords, crate name or full words in the description.

If partial matches were returned too, it would already solve a lot of issues. If you search for book you get 6 results, but if you search for boo you get nothing.

Also I think an exact match with the crate name should appear as the very first result.

Could use a little influence from number of downloads as well - arguably if you search for 'random' you'd probably want the 'rand' crate at least appearing in the top two results. It's number 4 at the moment (so clearly not too bad!), but one could imagine other situations in which this would be worse, particularly as the number of crates grows.

I might see if I can find some time to take a look at search.

But the results from cargo search file is super confusing because it doesn't say it truncated the list of matches by the first 10. I had the same problem with cargo search time. I'm filing another ticket on it.

DanielKeep commented 8 years ago

@nodakai Well, no; temp doesn't show tempfile, and file has too many results now to be useful, even if the results might contain tempfile (I gave up checking around result number 110).

nodakai commented 8 years ago

I see, so you're saying this package should have been found with the search for temp:

Yeah everyone would expect so.

I believe these SQL queries should be improved:
